A Winner's Creed

I bought this card when I was in my late teens to early 20's, so it's been around for a while. I haven't seen it for years but came across it the other day.

A Winner's Creed

If you think you are 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'll lose, you're lost;
For out in the world we find
success begins with a person's will
It's all in the state of mind.

Lif'e's battles don't always go
To the stronger or faster hand;
But sooner or later
The person who wins
Is the one who thinks "I can".
