Each of us bears his own Hell.

The measure of success is not whether you have a tough problem to deal with, but whether it's the same problem you had last year.

Waves are inspiring not because they rise and fall, but because each time they fall they never fail to rise again.

The ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy.

Mistakes are a fact of life. It is the response to error that counts.

Creativity is often blocked to trying to be perfect. Creativity is allowing yourself to make mistakes.

Feelings of worth can flourish only in an atmosphere where individual differences are appreciated, mistakes are tolerated, communication is open, and rules are flexible. The kind of atmosphere that is found in a nurturing family.
