"Read Euler, read Euler, he is the master of us all."

"The beauty of a mathematical proof lies not in its length but in its elegance."

"Life is but a moment, yet mathematics is eternal."

"In mathematics, you don't understand things. You just get used to them."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
