Show me a satisfied man, and I'll show you a failure.

Be a loner. That gives you time to wonder, to search for the truth. Have holy curiosity. Make your life worth living.

Anyone can be a genius, if they pick just one specific subject and study it diligently just 15 minutes each day.

Only a life lived for others is a life worth while . I have no special gift. I am only passionately curious . I want to know God's thoughts... all the rest are details. Joy in looking and comprehending is nature's most beautiful gift. It's not that I'm so smart , it's just that I stay with problems longer.

I do not believe in immortality of the individual, and I consider ethics to be an exclusively human concern with no superhuman authority behind it.

The most evident difference springs from the important part which is played in man by a relatively strong power of imagination and by the capacity to think, aided as it is by language and other symbolically devices.

With me every peep becomes a trumpet solo.
