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 a favoritism of 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 I 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 a 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 have to maintain
our physical health

and have to practice 
dental hygiene, right ?

We know 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? 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 rejections,
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 make 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 miss each other terribly .

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,

and it was the first we wouldn't
be spending together.

We decide to splurge, and that week,

we decided to talk for ten minutes.

I spend 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, 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 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 ringed 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 answer then,
but I do today,

and it's simple one: loneliness

Loneliness creates a
deep psychological wound,

one that distort 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 research on loneliness,
and all of it is horrifying.

Loneliness won't just make you
miserable, it will kill you.

I am 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 warning
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

and the cute doggie popped out,
and she squealed with delight.

So three toddlers with 
identical plastic toys,

but 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 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, you 
will stop try it too soon,

or you won't even try it at all. 
then you will be even more convinced

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 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 flash light on the driver,

and 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 dragged 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

you should see by the by look on his face,
that he was 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 are 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 really excited, and 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 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 am 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 priotize our

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
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's yells at you,

It's when your boss yells at you, or your 
professor makes you feel stupid in class,

you have big fight with your 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

with stage III Non-Hodgkin's lymphomaďź

his cancer was extremly aggressive ,

He has invisible tumors all over his body.

and he has to start harsh douse
of Chemo-Therapy,

and I couldn't stop thinking about 
what he is going through,

I could't stop thinking how much 
he is suffering. Even though

he never complained not once.

He has this incredible
positive attitude.

His psychological health is amazing.
I was physically healthy,

but Psychologically i was a mass.
but I knew what to do.

Studies tell us, even a two minutes
distraction is sufficient to break the

break the urge to Ruminate in
that moment.

So each time i had worrying and upsetting

negative thought, I force myself to concentrate
on something else

until the urge passed,
and within one week,

My whole outlook changed, and 
became more positive and more helpful.

Nine weeks after he started Chemo-Therapy,
my brother had Cat-scan,

I was by his side 
when he got back his results.

All the tumors were gone. He still has
three more Rounds Chemo-Therapy to go.

But we knew he would recover.

this picture was taken two weeks ago.

By taking action when you lonely,

by changing your response to failure,

by protecting yourself esteem,

by battling negative thinking,

You won't just heal your psychological 
wound,

you will bulid your emotional resilience,
you will thrive.

You know hundred years ago, 
People began practicing personal Hygiene,

and life expectancy rates rose by
over fifty percent in

just matter of decades. I believe
our quality of life

could rise just as dramatically if

we all begin practicing 
emotional Hygiene.

Can you imaging, can you imaging
what the world would be like

if everyone was 
psychologically healthier,

if there were less loneliness, 
and less depression.

If people knew how to overcome
failure,if they feel 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.
If you just become informed,

and change a few simple habits, well

and that's the world we all can live in.

Thank you very much.
