Some funny, some wise.
All generalizations are bad.
The probability of someone watching you is proportional to the stupidity of your action. He who commands the future conquers the past. Every day sends to their graves obscure men whose timidity prevented them from making a first effort. When you don't know where you're going any road will take you there. The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts.
