" If..."

The about short statement always very powerful, but depends on which direction you wish it to influent your life. I quoted this very famous quotes to proof it.

If you think you are beaten, you are;
If you think that you dare not, you don't;
If you'd like to win, but you think you can't,
It's almost certain you won't.

If you think you'll lose, you've lost;
For out in the world you'll find
Success begins with a fellow's will -
It's all in the state of mind.

If you think you are outclassed, you are;
You've got to think high to rise;
You've got to be sure of yourself before
You can ever win a prize.

Life's battles don't always go
To the stronger or faster man;
But soon or late the man who wins
Is the man who thinks he can."
