I'm looking at you, and you look like a really nice bunch.

There's been such great energy.

I was sitting here for five minutes, and it just feels great in this room.

You look really friendly enough, so thank you!

You are looking a bit unsure in a voice coach.

Don't worry, it's going to be fine.

And I can see a couple of really brainy TED faces there.

There's going to be a few ideas, too.

But it's this moment, when eyes, our worlds, are colliding right now.

You are looking at me, I am looking at you,

and it hits my brain with the feeling of adrenaline;

accelerating molecules, you might say.

Different people deal with this moment differently.

Some of us go, "Hey!", you know?

There are people who are confident,

they cope with this moment totally fine.

Then there are other people not so confident,

and it stops them from speaking this moment;

It makes them feel anxious, that maybe they are not up to it.

That is not the case.

Actually, all of us have confidence within.

What I want to talk about today

is the idea that we can find more confidence within us

if we know where to look.

Where do we look?

We go within. We look under the bonnet.

That's where we are going next.

And the reason I want to talk about this is because, many years ago,

I stood in front of an audience this big - bigger - at Central Hall,

which is by the Houses of Parliament, a really big Methodist space.

I was super excited about that moment

because I knew that it was my big moment as a rookie voice coach,

and I was going to be able to speak.

I stepped up in front of that audience,

and what happened was everything that could possibly go wrong did.

I went too fast, I lost my words.

It felt like such a horrible experience.

And just as I thought it couldn't go any worse,

the microphone broke.

I looked out across the room, and I said in my big voice coach voice,

- there wasn't so much wind at the time, I have to say -

(Laughter)

I said in my big voice coach voice, "Can you hear me at the back?"

And someone said, "Speak up!"

I felt this feeling of absolute shame.

That feeling of an audience looking at you,

and a feeling of judgment which cripples us.

I left that venue, and I thought to myself, "Never again."

Clearly that didn't work because I am here.

I also thought I am going to do it differently next time.

I will make sure that next time I stand up to speak, it feels good.

Where I had to go was within.

We live in a really visual culture.

We spend a lot of time - if you think about two worlds -

we spend a lot of time thinking about the outside.

Maybe especially for women.

Actually, confidence doesn't exist on the outside;

It exists within, in the visceral stuff,

in the bits within you that we don't see.

We are going to go to those bits.

When I was thinking about this idea three months ago,

when I was asked to do it,

I started to feel nervous about this moment,

I started to think about a quote

the director Peter Brook had said

which is that we open new drawers in the self.

I started to think about a chest of drawers.

Then I came across this really cool maker

called George McCallum, who is actually sitting there.

I said to George, "Can you make me a chest of drawers?

And he did.

You might be wondering what this object is.

And what this object is here is what George made.

But when you ask a maker to make a chest of drawers,

they don't always do what you think they are going to do.

Do you want to see what he did?

(Laughter)

Yeah! Thanks George. Best response of the morning.

Upstaged by the furniture.

(Laughter)

Within this little chest of drawers,

this rather big, manly chest of drawers,

are three secrets to finding confidence within.

Three lessons I had to learn on the way.

There is a big lesson in here.

The last lesson is the big one.

We are going to get there, and it's not what you might think.

It's a lesson that might surprise you.

But first, would you like to see inside the first drawer?

(Audience) Yes!

CG: It's a bit delicate this; George.

So what we have in here is an instrument.

Because you just been hearing the voice is the most amazing instrument.

It's magnificent.

How often do you think about how yours works?

Because like this little guitar, it has a string, and it has a hitter.

Where is the string of your voice?

Can you put a hand on it?

Here, give it a shake; it's your larynx.

Ahhhhh... Can everyone do that for meeee?

Ahhhhh!

The hitter is the air.

When you know that your voice is an instrument,

what does that tell you?

People come to me and say,

"I've a bad voice," "I am not a good speaker."

"I get worried about this kind of moment."

"I hate meetings," "I hate presentations," "Can't do it."

The voice is an instrument.

There is not such thing as a bad saxophone, is there?

Because when we hear a great saxophonist,

and he is probably somewhere down here,

what we know is that they've practiced a lot,

that not only did they have talent but also they have worked,

and worked, and worked to get a great sound.

If you ever doubt the sound of your voice,

let me tell you all you have to do is practice.

When I was worrying about that moment

I am going to call my central hall of shame, because it was,

what I remembered was the story of a guy in Ancient Greece

called Demosthenes.

There's a big old name,

so we're going to call him the Greek dude from now on,

which actually is also a bit of a big word,

so we might just call him Dave, I think.

(Laughter)

Dave was speaking at the Assembly which is like the O2.

We have Simon in the room.

It's like the Brixton Academy of the Ancient Greek world.

He was feeling pretty nervous. He wanted to be an orator.

Orators were the rock stars of their day.

So he geared himself up for this big moment at the Assembly,

and you know what?

He bombed.

They said he was uncouth in his speaking, and that he stammered.

So the audience jeered at him, and they threw stuff.

Please don't do that today!

(Laughter)

He left that stage feeling so downcast

when he got a bit of advice from an actor.

I'm sure Greek actors were pretty much the same as they are now.

I am sure the actor was a bit like this, but what he said to him was,

"You need more expression in your voice.

You are not giving enough welly, enough energy.

You also need to believe in yourself because the message is good."

Demosthenes takes himself back home, and he goes for it.

This is his rocky moment.

He builds himself an underground cellar.

He shaves his head - half of his head -

so that he can't leave the house for three months

and then he practices for three months solid

in front of a big shield that is polished like a mirror.

When he is ready, when he is up there,

he goes out.

He goes to the sea, and he speaks over the waves.

His voice has to boom out over the waves.

Then, he goes back. He goes back to the Assembly.

He speaks again,

and he becomes known as one of the greatest orators of his day.

What does that tell you?

It tells you about practice.

The power of practice.

You may not want to shave half of your head;

you may not want to build an underground cellar

because the council may have words,

but what you can do is practice.

And the simplest way to practice is to sing.

You don't have to do a big, "Mamamamahh!",

a voice coach warm-up - unless you want to -

but what I really recommend is that everyday sing somewhere:

sing in the shower, sing in the car, sing on the tube if you feel brave.

(Laughter)

I was at St Thomas' Hospital for a blood test about two weeks ago,

and there were two women singing in the space

where the blood test was happening which was lovely.

So I recommend it.

Singing is the way to a great voice.

Practice is the way to a great instrument.

That's lesson one.

We have another drawer which we will open in a moment,

but before we get there, I've a question.

Say you walk into a room, OK?

You don't know anybody.

Some of you may have had that feeling this morning.

How do you know who the most powerful person in the room is?

The person with the most confidence,

that inner confidence that we are going for here?

How could you tell?

How they carry themselves. That's lovely, [Lola].

You are in the same space, aren't you?

Because you are a singer.

It is that how they carry themselves.

Actually, what an actor will tell you is that is about the breath.

The most powerful person in the room has the most relaxed breathing pattern.

There is a well-known scientist called Paul Eckman who looks into emotion,

and he said - which would make actors laugh

because it seems so straightforward to them

that maybe isn't to science -

that he couldn't understand why breath mattered for a long time,

and his research has explored it,

until he started to understand that the unconscious system--

You know I can't control my spleen.

It is just doing its own thing.

But I can control my breathing.

And if I get into my breathing, I get into the unconscious.

I calm myself down.

So what's within you is the key to this relaxed, confident power.

Actors know this

because when actors are playing King, the King stays really still.

Everybody moves around the king,

and that's how you know the king is in charge.

The next time you fell nervous about something, try that; try getting still.

Within your body is something that is really the king of the body.

It's what the Greeks called the center of all expression.

I bet that 50% of this room has never thought about it.

Would you like to see what it is?

Thank you, my still handsome friend.

We've our lungs, don't we?

We have this, which is probably not an anatomical representation of a heart,

but it is nice.

(Laughter)

But what's down here? What's this?

(Audience) The diaphragm?

CG: Thank you very much! Diaphragm. It is indeed your diaphragm.

Put your hands up if you have thought about the diaphragm recently.

Put your hands up if you thought about your diaphragm today.

Thank you, singers in the room; good. Or actors, or saxophonists.

Put your hands up if you haven't yet thought about your diaphragm today.

Yeah, that is quite a large percentage.

So we don't think about our diaphragms, do we?

But the diaphragm is the key to regulating your system.

It is how you calm yourself down

in that moment when you stand in front of all the eyes.

It will make you feel confident

when you most need it, and you'd least feel like it.

I didn't know anything about my diaphragm.

I'd learned about it. I knew what it was supposed to look like,

but I didn't know how it felt.

Then one day,

I was feeling really stressed, I was breathing up in my chest.

I had that kind of squeaky high-voiced adrenaline breathing up in the chest;

Not good.

I walked into a yoga class, and the yoga teacher said,

"You look really stressed."

Which is never a good start.

He said, "Lie down on the floor."

And he laid me down, I closed my eyes,

expecting some lovely relaxing yoga thing,

and suddenly, he put a gym weight on my stomach.

And he said, "Breathe, lift that."

I did. I breathed in,
