Something to consider:

If You think You are beaten You are:
If You think You dare not, You don’t
If You 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
If You think you are 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 Individual:
But sooner or Later the Person who wins Is the Person who Thinks They Can!
