WEBVTT

00:00:14.175 --> 00:00:16.315
We have incredible potential.

00:00:17.176 --> 00:00:19.186
But how much do we really know

00:00:19.186 --> 00:00:24.025
about what are the most effective ways
for us to extract this potential?

00:00:24.025 --> 00:00:26.746
To overcome obstacles?
To reach our goals?

00:00:26.746 --> 00:00:29.656
To change as we need
to change along the way?

00:00:29.656 --> 00:00:31.617
To learn? To evolve?

00:00:31.996 --> 00:00:34.967
I'm a professor of computer science,

00:00:34.967 --> 00:00:38.188
and my area of research
is quantum computation.

00:00:39.229 --> 00:00:41.599
Those are computers that don't exist yet.

00:00:41.599 --> 00:00:45.350
But imagine computers
that will take one second

00:00:45.350 --> 00:00:47.720
to solve certain computational tasks

00:00:47.720 --> 00:00:50.360
that the fastest
supercomputer in the world

00:00:50.360 --> 00:00:53.010
will take zillions of years to solve.

00:00:53.420 --> 00:00:55.110
Thousands of researchers

00:00:55.110 --> 00:00:58.230
all over the world are now trying
to build those computers,

00:00:58.230 --> 00:01:01.916
and also trying to understand
what you will be able to do with them

00:01:01.916 --> 00:01:04.512
if and when we manage to build them.

00:01:05.622 --> 00:01:08.822
I deal with difficult challenges
on a daily basis.

00:01:08.822 --> 00:01:12.838
I'm really interested
in trying to find ways

00:01:12.838 --> 00:01:16.972
to overcome obstacles, and learning,
which are more effective.

00:01:18.942 --> 00:01:22.642
Now, during my career
I've had ups and downs.

00:01:23.712 --> 00:01:26.961
I was fortunate enough to have
a very, very successful PhD.

00:01:26.961 --> 00:01:31.204
But immediately after my PhD,
I went into this numb period

00:01:31.204 --> 00:01:34.133
in which nothing seemed to actually work,

00:01:35.011 --> 00:01:37.722
even though I was putting
a lot of effort into it.

00:01:38.482 --> 00:01:41.142
My friend came to me and told me

00:01:41.592 --> 00:01:47.115
"Dorit, you've painted
a very beautiful picture in your PhD.

00:01:47.115 --> 00:01:48.995
But you're putting in too much effort.

00:01:49.685 --> 00:01:54.966
Maybe it's time to let go, sign it up,
and move on to the next picture."

00:01:55.285 --> 00:01:58.480
And he was right; I was clinging
to it with all my might.

00:01:58.480 --> 00:02:00.604
I was applying a lot of force.

00:02:00.604 --> 00:02:02.744
That's one way of applying force.

00:02:03.084 --> 00:02:06.206
But we do that all the time
in many, many different contexts

00:02:06.206 --> 00:02:08.552
and many variations.

00:02:08.982 --> 00:02:11.376
Imagine yourself opening a drawer.

00:02:11.886 --> 00:02:13.256
You try to open it.

00:02:13.256 --> 00:02:14.506
It doesn't open.

00:02:14.816 --> 00:02:15.640
It's stuck.

00:02:15.640 --> 00:02:16.856
What do you do?

00:02:16.856 --> 00:02:18.147
You try harder.

00:02:18.147 --> 00:02:21.177
And if it doesn't work,
you try even harder.

00:02:21.177 --> 00:02:22.667
It might even break.

00:02:23.597 --> 00:02:25.885
You tell yourself
you have to finish an exercise,

00:02:25.885 --> 00:02:28.027
so you force yourself to do it.

00:02:28.027 --> 00:02:32.656
You want to go on a diet,
you force yourself to do it.

00:02:32.826 --> 00:02:34.506
You need to finish this book

00:02:34.506 --> 00:02:37.446
that's been lying
near your bed for a month,

00:02:37.446 --> 00:02:39.366
you force yourself to do it.

00:02:39.647 --> 00:02:44.468
I'm not saying that as a criticism,
it's just an observation.

00:02:44.468 --> 00:02:47.929
We see this all around us,
it's something very natural for us to do,

00:02:47.929 --> 00:02:50.658
and that's what we've probably
been told to do

00:02:50.658 --> 00:02:53.119
many times when we were very young.

00:02:54.057 --> 00:02:58.537
But we lose a lot
from this forceful approach.

00:02:58.537 --> 00:03:00.418
We lose a lot in quality.

00:03:00.908 --> 00:03:03.958
We lose our sensitivity, our creativity.

00:03:03.958 --> 00:03:08.138
Imagine a kid who hates mathematics

00:03:08.138 --> 00:03:11.737
and is forced to do
a mathematical exercise.

00:03:11.737 --> 00:03:13.883
It's not a very pretty
sight to see, right?

00:03:13.883 --> 00:03:16.368
It's not inspiring.

00:03:16.368 --> 00:03:19.558
It's as if some other part
of his brain has taken over him,

00:03:19.558 --> 00:03:23.788
and it's doing the job
but it's doing it very, very poorly.

00:03:24.492 --> 00:03:30.240
But there's a different kind
of thinking and learning

00:03:30.460 --> 00:03:34.369
which is much more connected to ourselves,
and much more attentive,

00:03:35.949 --> 00:03:37.639
and of a much higher quality -

00:03:37.969 --> 00:03:41.157
something which is much more connected,
much more attentive;

00:03:42.387 --> 00:03:44.948
it's more sensitive and more creative.

00:03:44.948 --> 00:03:50.609
I want to give you an experience
of such a learning and thinking process

00:03:50.609 --> 00:03:52.139
which is not forced.

00:03:59.969 --> 00:04:03.429
I'm holding a glass of water
here in front of you,

00:04:03.429 --> 00:04:06.790
and I'm going to rotate
this glass around itself

00:04:06.790 --> 00:04:11.305
without spilling the water, and without
detaching my hand from the glass.

00:04:11.305 --> 00:04:12.871
Here, watch me do it.

00:04:16.391 --> 00:04:18.101
Good, worked the first time.

00:04:19.894 --> 00:04:21.480
Now I have a question for you.

00:04:22.280 --> 00:04:25.071
How many times did the glass
rotate around itself?

00:04:25.511 --> 00:04:27.341
I'll let you watch me do it again.


00:04:27.341 --> 00:04:28.571
Watch carefully.

00:04:31.891 --> 00:04:32.995
Okay.

00:04:37.321 --> 00:04:39.600
It doesn't matter;
the answer doesn't matter.

00:04:39.600 --> 00:04:45.372
The point is that my question - if you're
curious and intrigued by the movement -

00:04:45.372 --> 00:04:49.852
my question triggered some spontaneous
thinking process inside you

00:04:49.852 --> 00:04:52.622
that was unforced.

00:04:52.622 --> 00:04:55.181
It was something
connected to your curiosity

00:04:55.181 --> 00:04:57.632
and something that came from within.

00:04:58.341 --> 00:05:00.662
The answer, by the way, is two.

00:05:02.192 --> 00:05:06.152
I'm looking for ways to maintain
those kind of qualities -

00:05:06.152 --> 00:05:10.822
sensitivity, creativity -
those connections within us,

00:05:10.822 --> 00:05:13.802
not only with such simple exercises,

00:05:13.802 --> 00:05:18.443
but also in front of the hardest obstacles
that we want to overcome.

00:05:18.873 --> 00:05:21.773
For that matter, let me
move on to my other passion.

00:05:22.193 --> 00:05:24.892
I've done body-mind methods for years.

00:05:24.892 --> 00:05:29.422
I practice tai chi,
king fu, yoga, Feldenkrais.

00:05:29.782 --> 00:05:34.083
One day, my kung fu teacher came to me,
it was while I was doing this kick.

00:05:34.953 --> 00:05:36.073
And he told me,

00:05:36.073 --> 00:05:40.304
"Dorit, pay attention to how
you return your leg back from the kick."

00:05:41.424 --> 00:05:46.045
Now, actually, I never even knew
I'm returning my leg back from the kick.

00:05:46.045 --> 00:05:49.830
It always seemed to me like my kick
ended with my leg up in the air,

00:05:49.830 --> 00:05:51.644
and the rest didn't exist.

00:05:52.169 --> 00:05:57.567
And then it occurred to me,
it's exactly how I operate in life.

00:05:57.567 --> 00:05:59.465
I throw myself into challenges,

00:05:59.465 --> 00:06:02.635
and then I don't care about
how I come back from them.

00:06:03.656 --> 00:06:06.896
What we do with our physical body,
our physical patterns,

00:06:06.896 --> 00:06:12.327
are actually intimately connected
to how we interact with life in general.

00:06:13.110 --> 00:06:18.986
I want to give you four principles
I've extracted from body-mind methods.

00:06:19.376 --> 00:06:23.896
And those principles, I think,
are very useful for overcoming obstacles

00:06:23.896 --> 00:06:26.446
and learning in general

00:06:27.237 --> 00:06:33.027
while maintaining your sensitivity,
and creativity, and capabilities,

00:06:33.027 --> 00:06:35.518
even in front of very difficult obstacles.

00:06:35.518 --> 00:06:39.896
Now, those principles don't only apply
to physical movement,

00:06:39.896 --> 00:06:44.164
I think they apply to overcoming
challenges in general.

00:06:44.417 --> 00:06:47.576
In fact, they also apply
to my scientific research

00:06:47.576 --> 00:06:49.437
and for learning mathematics.

00:06:51.220 --> 00:06:55.087
I'm going to give you an example
coming from a Feldenkrais lesson

00:06:55.087 --> 00:06:57.860
and extract the principles
from it one by one.

00:06:58.776 --> 00:07:01.076
I'm just taking Feldenkrais as an example;

00:07:01.846 --> 00:07:04.948
I could have taken other
body-mind methods as well,

00:07:05.428 --> 00:07:07.848
but this is a particularly
illuminating example.

00:07:09.226 --> 00:07:12.544
You see here my Feldenkrais
teacher, Eilat Almagor,

00:07:12.940 --> 00:07:16.110
and she's giving a lesson
to a child called Yuval.

00:07:17.542 --> 00:07:23.691
Yuval came to the lesson with some kind
of asymmetry in the way he's sitting.

00:07:24.098 --> 00:07:27.903
He finds it difficult to lean
on his left sitting bone.

00:07:28.253 --> 00:07:30.353
He leans on his right sitting bone.

00:07:30.833 --> 00:07:35.822
That means that he can't take his right
leg to the right, like that, while sitting

00:07:35.822 --> 00:07:38.154
because he can't lift
his right sitting bone.

00:07:38.782 --> 00:07:40.744
By the end of the lesson, however,

00:07:40.744 --> 00:07:45.623
Yuval actually brings his right leg
to the right on his own.

00:07:45.623 --> 00:07:49.323
I want to give you the key steps
of what's going on in the lesson,

00:07:49.323 --> 00:07:52.345
and walk you through those key steps,

00:07:52.345 --> 00:07:55.233
and extract the principles one by one.

00:07:56.265 --> 00:07:57.985
(Video) Dorit Aharonov: Eilat starts

00:07:57.985 --> 00:08:00.335
by working with Yuval's
right sitting bone.

00:08:00.335 --> 00:08:02.315
Now this might seem counterintuitive

00:08:02.315 --> 00:08:06.274
because Yuval already knows
how to lean on his right sitting bone.

00:08:07.664 --> 00:08:09.836
(On stage) DA: You might think
that this means

00:08:09.836 --> 00:08:13.416
that he will actually move
further to the right.

00:08:13.416 --> 00:08:17.686
And indeed, a little bit later,
he does move further to the right.

00:08:18.196 --> 00:08:19.537
First principle:

00:08:19.537 --> 00:08:24.548
Start within your comfort zone,
and make it even more comfortable.

00:08:24.933 --> 00:08:28.207
The next thing that Eilat does,
is now that Yuval

00:08:28.207 --> 00:08:30.317
is very comfortable with where he is,

00:08:30.317 --> 00:08:36.429
she inserts one little new ingredient
into his scenario.

00:08:36.429 --> 00:08:41.412
She just lets him feel that he can
be supported in his left sitting bone.

00:08:42.238 --> 00:08:44.649
But this is done within his comfort zone.

00:08:45.859 --> 00:08:49.219
She just picks one
little thing to add to it.

00:08:49.700 --> 00:08:54.270
Pick a challenge which
is interesting, within your reach,

00:08:54.270 --> 00:08:56.480
not too easy, not too hard.

00:08:57.720 --> 00:09:00.809
The next thing that Eilat does
might look a bit weird.

00:09:00.809 --> 00:09:04.222
She lifts Yuval up in the air
and lets him fall,

00:09:04.222 --> 00:09:06.321
and she does it from various directions.

00:09:06.830 --> 00:09:08.161
Now what she actually does,

00:09:08.161 --> 00:09:12.161
is she takes him away
from what he has just learned,

00:09:12.161 --> 00:09:13.941
to lean on both his sitting bones,

00:09:13.941 --> 00:09:18.002
and lets him know that he can return back
to what he just learned

00:09:18.002 --> 00:09:19.589
from different directions.

00:09:19.899 --> 00:09:21.320
Third principle:

00:09:21.320 --> 00:09:23.581
Move away from your desired goal,

00:09:23.581 --> 00:09:26.131
and come back to it
from different directions.

00:09:26.891 --> 00:09:31.081
Now, you might have noticed
that during the whole time,

00:09:31.081 --> 00:09:36.128
Yuval continues to play,
and do various things, and move.

00:09:36.388 --> 00:09:39.171
It's all happening
within his comfort zone.

00:09:39.561 --> 00:09:42.847
He integrates everything
that he's learning into his own life.

00:09:42.847 --> 00:09:44.363
Fourth and last principle:

00:09:44.683 --> 00:09:47.523
Play with it, connect it
to everything you know,

00:09:47.523 --> 00:09:48.715
make it your own.

00:09:49.043 --> 00:09:54.172
A little bit later, Yuval takes his leg
to the right on his own.

00:09:54.432 --> 00:09:57.132
The movement has already become his own.

00:09:57.643 --> 00:09:59.843
I want to repeat those four principles.

00:10:00.703 --> 00:10:04.453
Start within your comfort zone
and make it even more comfortable.

00:10:05.973 --> 00:10:07.133
Second principle:

00:10:07.773 --> 00:10:09.772
Not too easy, not too hard:

00:10:09.772 --> 00:10:12.722
Pick an interesting challenge
within your reach.

00:10:14.193 --> 00:10:15.289
Third principle:

00:10:15.289 --> 00:10:20.079
Move away from your desired goal,
and come back to it from different angles.

00:10:20.649 --> 00:10:22.044
Fourth principle:

00:10:22.044 --> 00:10:24.734
Play with it, connect it,
make it your own.

00:10:25.888 --> 00:10:31.174
Okay, now these principles,
they're effective, as you've seen,

00:10:31.174 --> 00:10:33.002
in the context of movement.

00:10:33.002 --> 00:10:36.304
But I find them to be very, very effective
also in other contexts.

00:10:36.304 --> 00:10:38.874
And in particular,
in my scientific research,

00:10:38.874 --> 00:10:41.144
and in the context
of mathematics in general.

00:10:41.484 --> 00:10:43.159
Now, I want to give you an example

00:10:43.159 --> 00:10:46.873
of how to use those principles
in the context of mathematics,

00:10:47.483 --> 00:10:49.173
in the context of a small riddle.

00:10:50.004 --> 00:10:52.314
Once upon a time, there was a queen.

00:10:53.638 --> 00:10:57.704
The queen ruled her island because
she was the only one on the island

00:10:57.704 --> 00:10:59.914
who knew how to do the following trick.

00:10:59.914 --> 00:11:03.343
She had two cubes;
each cube had six faces,

00:11:03.343 --> 00:11:05.723
and on each face,
there is a digit written.

00:11:06.154 --> 00:11:09.643
Now, what she knew
how to do with those cubes

00:11:09.643 --> 00:11:15.444
is she knew how to represent
all dates in the month with those cubes.

00:11:15.928 --> 00:11:20.674
Now, this is a bit confusing because
there are only six faces on each cube,

00:11:20.674 --> 00:11:22.933
and there are ten digits to write on them,

00:11:22.933 --> 00:11:24.603
so how did she do that?

00:11:25.183 --> 00:11:30.458
I want to solve this riddle with you
using the principles that I've just shown,

00:11:30.458 --> 00:11:34.810
and I'll have this place here
at the top corner of the screen

00:11:34.810 --> 00:11:37.973
where the principle
that we're now using will be written.

00:11:39.042 --> 00:11:40.924
So that you can keep track of it.

00:11:41.634 --> 00:11:43.345
We start with what we need to do.

00:11:44.549 --> 00:11:49.136
We need to write six digits on each cube
so I make space for those digits,

00:11:49.576 --> 00:11:50.796
six for each cube.

00:11:51.221 --> 00:11:54.715
Now let's start
with a very, very small step.

00:11:54.715 --> 00:11:58.025
Let's just write the first date - 01.

00:11:58.556 --> 00:12:02.336
So we need a 0 on the first cube,
and we need a 11 on the second cube

00:12:02.336 --> 00:12:03.556
so we do that.

00:12:03.916 --> 00:12:07.736
Well that was easy enough,
so let's continue this way.

00:12:08.376 --> 00:12:13.355
We can also write 02, 03, 04, 05.

00:12:15.115 --> 00:12:19.485
Okay, but we can't continue like that
for all dates that start with 0,

00:12:19.485 --> 00:12:22.126
there's just not enough room
in the right cube.

00:12:22.396 --> 00:12:27.465
So now we see that we can
identify a simple goal

00:12:27.465 --> 00:12:30.608
that is still something interesting
that we don't know how to do.

00:12:31.330 --> 00:12:36.883
Let's try to represent
all the dates that start with 0 -

00:12:37.277 --> 00:12:39.316
the left-most column.

00:12:40.994 --> 00:12:45.258
We see that we can't just do that
with just one 0 on one cube,

00:12:45.258 --> 00:12:48.718
but if we add one 0 on the right cube,

00:12:48.718 --> 00:12:52.458
then you can combine it
with all the digits

00:12:52.458 --> 00:12:54.989
by putting all the other digits
on the left cube.

00:12:54.989 --> 00:12:57.338
So now we are done with the left column.

00:12:58.189 --> 00:13:03.129
But we can take this idea of having
0 on both cubes to the next column.

00:13:04.528 --> 00:13:06.346
We can solve now for the next column

00:13:06.346 --> 00:13:10.147
which consists of all numbers
that start with 1,

00:13:10.147 --> 00:13:12.519
by just putting 1 on both cubes.

00:13:13.449 --> 00:13:17.019
We can do that because we have more room,
we add a 1 to the left cube,

00:13:17.019 --> 00:13:18.529
and now we have 1 on both cubes

00:13:18.529 --> 00:13:21.338
and we can do all combinations
with all the other digits.

00:13:21.738 --> 00:13:24.152
So that's fine for the second column.

00:13:24.518 --> 00:13:26.489
Now we want to do the third column.

00:13:27.118 --> 00:13:29.940
So if we can put 2 on both cubes,
that would be great,

00:13:29.940 --> 00:13:31.441
but we don't have more room.

00:13:31.841 --> 00:13:33.140
So now what do we do?

00:13:33.420 --> 00:13:38.291
Well, we use the next principle,
and we make a deliberate mistake.

00:13:38.291 --> 00:13:43.052
We move away from our target and we add 2,
even though we don't have room for that.

00:13:43.550 --> 00:13:45.260
Maybe we can correct for it later.

00:13:45.831 --> 00:13:49.391
Okay, so now we have 2 on the left cube,

00:13:49.391 --> 00:13:52.791
and you can check that
you can now write all the 20s,

00:13:53.161 --> 00:13:56.120
and you can also see
that you can write 30 and 31.

00:13:56.910 --> 00:14:00.491
Great, but now we have
seven digits on the left cube.

00:14:00.491 --> 00:14:02.730
So how do we correct for that?

00:14:05.520 --> 00:14:09.032
I need all the digits on the left cube,
so what do I do?

00:14:09.782 --> 00:14:13.652
Now I want to use the fourth principle:
I want to play with it.

00:14:15.152 --> 00:14:17.466
So let's get serious with playing.

00:14:19.284 --> 00:14:23.245
I brought here with me
two colorful cubes from that island,

00:14:23.625 --> 00:14:25.898
and I want to play with them.

00:14:26.327 --> 00:14:30.865
I'm going to play with them,
and I can write here -

00:14:31.135 --> 00:14:32.771
they're going to break, actually -

00:14:32.771 --> 00:14:35.965
okay, I have a 2 here;
I can write 20-something.

00:14:36.306 --> 00:14:37.485
Let's see.

00:14:37.835 --> 00:14:39.600
I can write 21.

00:14:39.885 --> 00:14:41.416
I can write 27.

00:14:41.781 --> 00:14:44.276
I can write 26.

00:14:45.146 --> 00:14:46.286
29!

00:14:46.286 --> 00:14:48.545
Right, I can also write 29.

00:14:48.784 --> 00:14:51.055
Aha, you've got it already.

00:14:51.265 --> 00:14:55.095
I don't need the 6 and 9.

00:14:56.670 --> 00:14:58.906
And that's the solution.

00:14:59.809 --> 00:15:02.095
Now, you might be thinking,

00:15:02.095 --> 00:15:06.285
"Hmm, is this all it takes
to be a quantum computer scientist?

00:15:06.598 --> 00:15:08.976
Just rotate colorful cubes

00:15:08.976 --> 00:15:12.765
and lift your right and left
sitting bone once in a while,

00:15:12.765 --> 00:15:15.696
and follow your butt once in a while?"

00:15:15.696 --> 00:15:17.966
Well, the answer is...

00:15:18.386 --> 00:15:19.836
honestly, yes.

00:15:22.506 --> 00:15:25.046
Now seriously, I strongly believe

00:15:25.046 --> 00:15:30.855
that all scientific discoveries,
great or small,

00:15:30.855 --> 00:15:34.286
can be boiled down
to a very small, little step

00:15:34.286 --> 00:15:37.715
of maybe a twist or a rotation
around what you thought before,

00:15:37.715 --> 00:15:40.935
or looking at things
from a different angle,

00:15:40.935 --> 00:15:43.515
or making an unexpected connection.

00:15:44.065 --> 00:15:48.255
And playing with it
will reveal those things.

00:15:48.746 --> 00:15:53.387
And this is exactly what we're doing now
in the area of quantum computation.

00:15:53.387 --> 00:15:57.927
In this area, we are actually at the state
of Yuval in the beginning of the lesson.

00:15:57.927 --> 00:16:00.499
We don't know yet
how to build those computers.

00:16:00.499 --> 00:16:04.057
And we don't know yet
what we will be able to do with them,

00:16:04.057 --> 00:16:06.267
if and when they're built.

00:16:06.267 --> 00:16:10.948
But what we're doing is,
we start within our comfort zone,

00:16:10.948 --> 00:16:14.299
we look around to see
where we can expand it,

00:16:14.299 --> 00:16:16.083
where we can find challenges

00:16:16.083 --> 00:16:18.382
within our reach
that are still interesting,

00:16:18.382 --> 00:16:20.628
and once we find them
and manage to get them,

00:16:20.628 --> 00:16:22.450
we try to understand it further,

00:16:22.450 --> 00:16:25.491
we try to go back and forth
in order for it to be reliable.

00:16:25.491 --> 00:16:27.751
We try to fall on it
from different directions,

00:16:27.751 --> 00:16:29.960
and we keep continuing to play.

00:16:30.230 --> 00:16:34.160
And that is something
that has already been very useful,

00:16:34.160 --> 00:16:36.780
even without reaching
our goals, our big goals,

00:16:36.780 --> 00:16:39.060
we already found very,
very interesting things

00:16:39.060 --> 00:16:43.042
and many new areas have been opened,
and many new connections,

00:16:43.042 --> 00:16:44.513
just by this approach.

00:16:44.783 --> 00:16:50.436
Do you have a goal in your life
that you haven't managed to move

00:16:50.686 --> 00:16:53.913
or make progress on for a long time?

00:16:54.128 --> 00:16:56.404
I invite you to check - maybe...

00:16:56.594 --> 00:16:57.903
maybe...

00:16:57.903 --> 00:17:00.734
you're putting just too much energy

00:17:00.734 --> 00:17:04.284
in a direction that you expect
things to move.

00:17:04.544 --> 00:17:10.476
And maybe by reducing the amount of force
and letting it move in other directions,

00:17:10.476 --> 00:17:12.654
you might find yourself
in a different place

00:17:12.654 --> 00:17:15.224
which could be very close
to where you are now,

00:17:15.224 --> 00:17:18.666
but it will be a different place
from which things will look different.

00:17:19.626 --> 00:17:25.496
I find that resisting the temptation
of using the forceful approach

00:17:25.496 --> 00:17:27.975
is a lifelong process of awareness,

00:17:27.975 --> 00:17:29.595
but I think it's worthwhile

00:17:29.595 --> 00:17:33.686
because you gain your sensitivity,
your creativity, your liveliness,

00:17:33.686 --> 00:17:35.607
in front of difficult obstacles.

00:17:35.607 --> 00:17:38.037
And even if you don't reach
what you wanted,

00:17:38.037 --> 00:17:41.887
well, you reach other places
which could be as interesting.

00:17:42.567 --> 00:17:43.946
Thank you for listening.

00:17:43.946 --> 00:17:46.475
(Applause)

00:17:46.475 --> 00:17:47.627
(Whistles)

00:17:47.627 --> 00:17:49.237
(Cheers)
