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."

"Face your fears with courage."

"You can't live your life in fear."

"Snakes. Why'd it have to be snakes?"

"Fear is just another obstacle to overcome."
