What great thing would you attempt if you knew you could not fail?

Men must live and create. Live to the point of tears.

Wonder rather than doubt is the root of all knowledge.

Only those who have learned the power of sincere and selfless contribution experience life's deepest joy: true fulfillment.

It is not ignorance but knowledge which is the mother of wonder.

If you accept the expectations of others, especially negative ones, then you never will change the outcome.

I am prepared for the worst, but hope for the best.

God sleeps in the minerals, awakens in plants, walks in animals, and thinks in man.

Everyone here has the sense that right now is one of those moments when we are influencing the future.

The glow of one warm thought is to me worth more than money.
