Be yourself; everyone else is already taken

A cynic is a man who knows the price of everything and the value of nothing

Cynicism mistakes cost for worth

I can resist everything except temptation

Self-aware confession of human weakness

The reports of my death have been greatly exaggerated

Premature announcements of one's demise are wrong

I have never let my schooling interfere with my education

Formal education is not the only—or best—form of learning

The definition of insanity is doing the same thing over and over and expecting different results

Repetition without change produces no change

In the middle of difficulty lies opportunity

Crises create openings for those who see them
