It's all in a state of mind

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

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

For many a game is lost
Ere even before a play is run,
And many a coward fails
Ere even his work is begun.

Think big and your deeds will grow;
Think small and you'll fall behind;
Think that you can and you will;
It's all in a state of mind.

If you think you're out classed 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 fellow who thinks he can!
