Quote by William H. McCallum

"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."

"I believe in working hard for what you want."

"Never underestimate the power of determination."

"I don't need a reason to fight."

"The most important thing is the mission. Nothing else matters."
