Never take the advice of someone who has not had your kind of trouble.

A cynic is not merely one who reads bitter lessons from the past, he is one who is prematurely disappointed in the future.

The time to relax is -- when you don't have time for it.

Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable.

Nothing can be so amusingly arrogant as a young man who has just discovered an old idea and thinks it is his own.

We have not passed that subtle line between childhood and adulthood until we move from the passive voice to the active voice -- that is, until we have stopped saying "It got lost," and say, "I lost it.".
