Life isn't worth living, unless it is lived for someone else... - Albert Einstein

"Reality is merely an illusion, albeit a very persistent one."

"There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle."

"Never memorize something that you can look up."

"If at first the idea is not absurd, then there is no hope for it."

"Do not worry about your difficulties in Mathematics. I can assure you mine are still greater."
