The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.
No man ever got very high by pulling other people down. The intelligent merchant does not knock his competitors. The sensible worker does not work those who work with him. Don’t knock your friends. Don’t knock your enemies. Don’t knock yourself.
Intelligence is like four-wheel drive. It allows you to get stuck in more remote places.
