Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.
