Thinking

If you think you are beaten, you are.

If you think you dare not, you don't.

If you would like to win but think you can't, it is 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 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 man who thinks he can.
