I grew up with my identical twin,
who was an incredibly loving brother.
Now one thing about being a twin is
that it makes you an expert
at spotting favoritism.
If his cookie was even slightly bigger
than my cookie, I had questions.
And clearly, I wasn't starving.
(Laughter)
When I became a psychologist, I began to
notice favoritism of a different kind,
and that is how much more we
value the body than we do the mind.
I spent nine years at university earning
my doctorate in psychology,
and I can't tell you how many people
looked at my business card and said,
"Oh, a psychologist, so not a real doctor",
as if it should say that on my card.
(Laughter)
This is the favoritism we
show the body over the mind.
I see it everywhere.
I recently was at a friend's house,
and their five-year-old
was getting ready for bed.
He was standing on a stool
by the sink and brushing his teeth,
when he slipped, and scratched his leg
on the stool when he fell.
He cried for a minute, but
then he got back up,
got back on the stool and reach out
for a box of band-aids
to put one on his cut.
Now this kid could barely
tie his shoe laces,
but he knew you have to cover a cut,
so it doesn't become infected,
and you have to care for
your teeth by brushing twice a day.
We all know how to maintain
our physical health
and have to practice
dental hygiene, right ?
We've known it since
we were five-years-old.
But what do we know about maintaining
our psychological health?
Well, nothing.
What do we teach our children
about emotional hygiene?
Nothing.
How is it that we spend more time
taking care of our teeth
than we do our minds.
Why is it that our physical health is
so much more important to us
than our psychological health?
You know, we sustain psychological injuries
even more often than we do physical ones,
injuries like failure or rejection,
or loneliness.
And they can also get
worse if we ignore them,
and they can impact our lives
in dramatic ways.
And yet, even though there are
scientifically proven techniques
we could use to treat these
kinds of psychological injuries,
we don't.
It doesn't even occur to us
that we should.
"Oh, your feeling depressed,
just shake it off, it's all in your head."
Can you imagine say that to
somebody who broken a leg,
"Just walk it off, it's all in your leg."
(Laughter)
It is the time we close the gap between
our physical and our psychological health.
It's time we made them more equal,
more like twins.
Speaking of which, my brother
is also a psychologist.
So he's not a real doctor, either.
(Laughter)
We didn't study together, though.
In fact, the hardest thing I've
ever done in my life
is move across Atlantic to New York City
to get my doctorate in psychology.
We were apart then, for the
first time in our lives,
and the separation was
brutal for both of us.
But while he remained among
family and friends,
I was alone in a new country.
We missed each other terribly,
but international phone calls were
really expensive then
and we could only afford to speak
for five minutes a week.
When our birthday rolled around,
it was the first we wouldn't
be spending together.
We decide to splurge, and that week,
we would to talk for ten minutes.
I spent morning passing around
my room, waiting for him to call.
And waiting, and waiting,
but the phone didn't ring.
Given the time difference, I assumed,
"Ok, he 's out with friends,
he will call later."
There were no cell phones then.
But he didn't.
And I began to realize that after
being away for over 10 months,
he no longer missed me
the way I missed him.
I knew he would call in the morning,
but that night was one of the
saddest and longest nights of my life.
I woke up the next morning.
I glanced down at the phone, and
I realized I had kicked it off the hook
when pacing the day before.
I stumbled out off bed,
I put the phone back on the receiver,
and it rang a second later,
and it was my brother,
and boy he was pissed.
(Laughter)
It was the saddest and longest
night of his life as well.
Now I tried to explain what
happened, but he said,
"I don't understand, if you saw
I wasn't calling you,
why didn't you just pick up
the phone and call me?"
He was right. Why didn't I call him?
I didn't have an answer then,
but I do today,
and it's simple one: loneliness
Loneliness creates a
deep psychological wound,
one that distorts our perceptions
and scrambles our thinking.
It makes us believe that those around
us care much less than they actually do.
It make us really afraid to reach out,
because why set yourself up
for rejection and heartache
when your heart is already aching
more than you can stand?
I was in the grips of real
loneliness back then,
but I was surrounded by people all day,
so it never occurred to me.
But loneliness is defined
purely subjectively.
It depends solely on whether you feel
emotionally or socially disconnected
from those around you.
And I did.
There is a lot of research on loneliness,
and all of it is horrifying.
Loneliness won't just make you
miserable, it will kill you.
I'm not kidding.
Chronic loneliness increases your
likelihood of an early death
by 14 percent,14 percent.
Loneliness causes high blood pressure,
high cholesterol.
It even suppress the functioning
of your immune system,
making you vulnerable to all kinds
of illnesses and diseases.
In fact, scientists have concluded
that taken together,
chronic loneliness poses as
significant a risk
for your longterm health and
longevity as cigarette smoking.
Now cigarette packs come with warnings
saying, "This will kill you."
But loneliness doesn't.
And that's why it's so important that
we prioritize our psychological health,
that we practice emotional hygiene.
Because you can't treat
a psychological wound
if you don't even know you're injured.
Loneliness isn't the only psychological
wound that distorts our perceptions
and misleads us.
Failure does that as well.
I once visited a day care center,
where I saw three toddlers
play with identical plastic toys:
you had to slide the red button,
and a cute doggie would pop out.
One little girl tried pulling the
purple button, then pushing it,
and then she just sat back and looked
at the box, with her lower lip trembling.
The little boy next to her
watched this happen,
then turned to his box and and burst
into tears without even touching it.
Meanwhile, another little girl tried
everything she could think of
until she slid the little red button,
the cute doggie popped out,
and she squealed with delight.
So three toddlers with
identical plastic toys,
but with very different
reactions to failure.
The first two toddlers were perfectly
capable of sliding a red button.
The only thing that prevented
them from succeeding
was that their mind tricked them
into believing they could not.
Now adults get tricked this way
as well, all the time.
In fact, we all have a default set of
feelings and beliefs that gets triggered
whenever we encounter
frustrations and setbacks.
Are you aware how your mind
reacts to failure?
You need to be.
Because if your mind tries to convince
you that you're incapable of something
and you believe it, then like
those two toddlers,
You'll begin to feel helpless and
you'll stop try it too soon,
or you won't even try it at all.
And then you'll be even more convinced
that you can't succeed.
You see, that's why so many people
function below their actual potential.
Because somewhere along the way,
sometimes a single failure
convinced them that they couldn't
succeed, and they believed it.
Once we become to convinced of something,
it's very difficult to change our mind.
I learn that lesson the hard way
when I was a teenager with my brother.
We were driving with friends
down a dark road at night,
when a police car stopped us.
There had been a robbery in the area
and they were looking for suspects.
The officer approached the car, and he
shined his flashlight on the driver,
then on my brother in the front seat,
and then on me.
And his eyes opened wide and he said,
"Where have I seen your face before?"
(Laughter)
And I said, "In the front seat."
(Laughter)
But that made no sense
to him whatsoever.
So now he thought I was on drugs.
(Laughter)
So he drags me out of the car,
he searches me,
he marches me over to the police car,
and only when he verified that I don't
have a police record,
could I show him that I had
a twin in the front seat.
But even we were driving away,
you could see by the look on his face
that he was convinced that I was
getting away with something.
Our mind is hard to change once
we become convinced.
So it might be very natural to feel
demoralized and defeated after you fail.
But you cannot allow yourself to become
convinced that you can't succeed.
You have to fight feelings
of helplessness.
You have to gain control
over the situation.
And you have to break this kind of
negative cycle before it begins.
Our minds and our feelings,
they're not the trustworthy friends
we thought they were.
They are more like a really moody friend,
who can be totally supportive one minute,
and really unpleasant the next.
I once worked with this woman who
after 20 years marriage
and an extremely ugly divorce, was
finally ready for her first date.
She has met this guy online, and
he seemed nice and he seemed successful,
and most importantly,
he seemed really into her.
So she was very excited, she
bought new dress,
and they met at an upscale
New York City bar for a drink.
Ten minutes into the date, the man
stands up and says,
"I'm not interested." and walks out.
Rejection is extremely painful.
The woman was so hurt, she could't move.
All she could do is call a friend,
here's what friend said,
"Well, what do you expect?
You have big hips, you have
nothing interesting to say.
Why would a handsome,
successful man like that
ever go out with a loser like you?"
Shocking that a friend could be so cruel.
But it would be much less shocking if I
told you it wasn't a friend who said that.
It's what the woman said to herself.
And that's something we all do,
especially after a rejection.
We all start thinking of our
faults and all our shortcomings,
what we wish we were,
what we wish we weren't,
we call ourselves names.
Maybe not as harshly, but we all do it.
And it's interesting that we do, because
our self-esteem is already hurting.
Why would we want to go
and damage it even further?
We wouldn't make a physical injury
worse on purpose.
You wouldn't get cut on your arm
and decide, "Oh, I know!
I'm going to take a knife and see
how much deeper I can make it."
But we do that with psychological
injuries all the time.
Why? Because of poor emotional hygiene.
Because we don't prioritize our
psychological health.
We know from dozens of studies
that when your self-esteem is lower,
you are more vulnerable to
stress and to anxiety.
That failures and rejections hurt more
and it takes longer to recover from them.
So when you get rejected, the first
thing you should be doing
is to revive your self-esteem, not join
fight-club and beat it into a pulp.
When you're in emotional pain,
treat yourself with same compassion you
would expect from a truly good friend .
We have to catch our unhealthy
psychological habits and change them.
One of unhealthiest and most common
is called rumination.
To ruminate means to chew over.
It's when your boss yells at you, or your
professor makes you feel stupid in class,
you have big fight with a friend
and you just can't stop replaying the
scene in your head for days,
sometimes for weeks on end.
Now ruminating about upsetting events
in this way can easily become a habit,
and it's a very costly one.
Because by spending so much time focused
on upsetting and negative thoughts,
you are actually putting yourself
at significant risk for developing
clinical depression, alcoholism,
eating disorders,
and even cardiac vesicular disease.
The problem is the urge to ruminate can
feel really strong and really important,
so it's a difficult habit to stop.
I know this for a fact, because
little over a year ago,
I developed the habit myself.
You see, my twin brother was diagnosed
with stage III Non-Hodgkin's lymphoma.
His cancer was extremly aggressive,
he had visible tumors all over his body.
And he had to start a harsh
course of chemotherapy.
And I couldn't stop thinking about
what he was going through,
I could't stop thinking how
much he was suffering,
even though he never complained, not once.
He had this incredibly positive attitude.
His psychological health was amazing.
I was physically healthy,
but psychologically, I was a mess.
But I knew what to do.
Studies tell us that even a two minute
distraction is sufficient
to break the urge to ruminate
in that moment.
And so each time I had worrying,
upsetting, negative thought,
I forced myself to concentrate on
something else until the urge passed.
And within one week, my whole
outlook changed
and became more positive
and more hopeful.
Nine weeks after he started chemotherapy,
my brother had a Cat scan,
and I was by his side when
he got the results.
All the tumors were gone.
He still had three more rounds
of chemotherapy to go,
but we knew he would recover.
This picture was taken two weeks ago.
By taking action when you're lonely,
by changing your responses to failure,
by protecting your self-esteem,
by battling negative thinking,
you won't just heal your
psychological wounds,
you will bulid your emotional resilience,
you will thrive.
You know 100-years-ago, people began
practicing personal hygiene,
and life expectancy rates rose
by over 50 percent
in just a matter of decades.
I believe our quality of life
could rise just as dramatically
if we all begin practicing
emotional Hygiene.
Can you imagine what
the world would be like
if everyone was psychologically healthier?
If there was less loneliness
and less depression?
If people knew how to overcome failure?
If they felt better about themselves
and more empowered?
If they were happier and more fulfilled?
I can, because that's the world
I want live in,
and that's the world my brother
wants to live in as well.
And if you just become informed
and change a few simple habits,
well, that's the world we can all live in.
Thank you very much.
(Applause)
