If you think you dare not, you don't,
If you like to win, but you think you can't,
It is almost certain you won't.
"If you think you'll lose, you are 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 soon or late the man who wins
Is the man WHO THINKS HE CAN!".

Definitions of purpose is the starting point from which one must begin.
The way of success is the way of continuous pursuit of knowledge.
A quitter never wins, and a winner never quits.
