The winners in life think constantly in terms of I can, I will, and I am. Losers, on the other hand, concentrate their waking thoughts on what they should have or would have done, or what they can't do.

Life is self-fulfilling prophecy.

You must continue to gain expertise, but avoid thinking like an expert.

The most important opinion you'll ever have is the one you hold of yourself.

You must accept responsibility for your actions, but not the credit for your achievements.

Your attitude is a choice you make.
