"The real contest is always between what you've done and what you're capable of doing."
"Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding."
"The best way to understand something is to try to explain it to someone else."
"A good teacher is like a candle - it consumes itself to light the way for others."
"In mathematics, you don't understand things. You just get used to them."
