If you think

 

If you think you are beaten, you are.
If you think you dare not, you don't.
If you like to win, but think you can't,
It's almost certain you won't.
If you think you'll lose, you're lost.
For out of the world we 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 win the prize.
Life's battles don't always go
To the stronger or faster man.
But sooner or later, the man who wins
Is the man who thinks he CAN.
