Nassim Nicholas Taleb
"Never tell people what to do; tell them what you do."

"If you see fraud and don't shout fraud, you are a fraud."

"There are a lot of people that unless they make a living lying down or standing up, they're not really free. If you're talking against banking system bonuses, and you're in banking, you're not really free. There are a lot of people who try to fit ethics to the profession, rather than fit the profession to their ethics. So they can work as lobbyists for a tobacco firm by saying, "Everybody's gotta make a living.""
