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

If you think you'll lose, you're lost,
For out of the world we find
Success begins with a fellows will
It's all in the state of mind

If you think your 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 stronger or faster men;
But soon or late the man who wins,
Is the one who thinks he can.
