It's 1903

and this extraordinary guy 
named Teddy Roosevelt

is standing on the edge 
of the Grand Canyon

and at that time people wanted
to create hotels and spas

and turn the Grand Canyon in 1903

intoa profit-making disneyland 
of the environment.

And he stood and said no.

And he created a tipping point for
the environmental movement

and for the world.

He said: "leave it as it is.

the ages have been at work on it 
and man can only mar it."

(Aplauses)

The world would have been
a different place today

without those words,
those tipping point words

from Presidente Theodore Roosevelt.

Fas forward his fifth cousin,
President Franklin Roosevelt,

30 years later - 1933 -
in the midst of a huge crises

the great Depression of America,
said a few words

to create a tipping point 
towards healing for the USA.

"First of all. Let me ask
certain my firm belief

that the only thing we have
to fear is fear itself

nameless unreasoning 
unjustified terror

which paralyzes needed up 
to convert it free and what that."

The world would have been
a different place

without those words at that time
from that man.

So in my 30 years of studying
in public speaking

and great speeches

I've found that 
there are seven secrets

that great speakers do 
that other people don't.

and it's my belief that 
every single human being

can be a great speaker 
and that their words

can create a tipping point,

and that their words and their
essencecan change the world.

The first secret is about words 
and understanding that words

can be the best, 
the most amazing in the world

but they only actually touch 
people and communicate

seven percent of the impact 
that one human being has on another.

Voice tone, the variation
in your voice, the enthusiams,

the love, the passion that 
comes through your voice,

38% percent your body language

are you looking into someone's eyes

or are you looking over their 
head and not connected.

So words, voice tone 
and body language,

those are the three vehicles,
the tree pathways

that great communication happens in.
