“Always do more than is required of you.”

“There is no need to always require a smile! Happiness is more of a look in the eyes, than a smile on the face!”

“The ethical person should do more then he is required to do, and less than he is allowed to.”

“There’s always less to do than you think. If there’s more to do than you think, then do that also.”

“Doing what you're supposed to do is always boring. I can't imagine anything worse than being required to have fun.”

“If you have more than one reason to do something (choose a doctor or veterinarian, hire a gardener or an employee, marry a person, go on a trip), just don’t do it. It does not mean that one reason is better than two, just that by invoking more than one reason you are trying to convince yourself to do something. Obvious decisions (robust to error) require no more than a single reason.”
