Jeffrey Kluger
When people are driving themselves crazy, they have neuroses or psychoses. When they drive other people crazy, they have personality disorders.
Albert J. Bernstein
Half the harm that is done in this world is due to people who want to feel important. . . .They justify it because they are absorbed in the endless struggle to think well of themselves.
T.S. Elliott
