self-discipline

“I don't believe in the words like never and always. Because I think that's a way of limiting yourself and self-discipline yourself makes you less free and less happy at some level.”

“If you wait till you feel like doing something, you'll never do it, and furthermore, if you give in to your feelings about a thing, you will give up on many things, because anything worth having requires hard work, and hard work, by definition, is not pleasant…”

“Self-discipline is the standard to which you hold yourself. That, to me, that's what moderation is, like, not what you can do, but what you allow yourself to do. Not what's legal, but what you choose.”

“So the discipline of an army sergeant is obviously important, but I don't think that's a virtue because it's being imposed on you.”
