A man who dares to waste one hour of time has not discovered the value of life.

All life is an experiment. The more experiments you make the better.

All the art of living lies in a fine mingling of letting go and holding on.

Any idiot can face a crisis - it's day to day living that wears you out.

Believe that life is worth living and your belief will help create the fact.

But now I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth.

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment.
