If you think you're beaten, you are;
If you think you dare not, you don't;
If you'd like to win, but think, you can't
It's almost a cinch you won't.
If you think you will lose, you're lost;
For out in the world we find,
Success begins with a fellow's will,
It's all in the state of mind.

If you think you're outclassed, you are;
You've got to think high to rise.
You've got to hustle before
You can ever win a prize.
Life's battles don't always go
To the stronger or faster man,
But sooner or later the man who wins
Is the one who thinks he can.
