Quote by Richard Feynman

"The first principle is that you must not fool yourself, and you are the easiest person to fool."

"What I cannot create, I do not understand."

"The pleasure of finding things out is the most important thing."

"You don't have to know everything to do something."

"Patience is a virtue I'm still learning."

"I may be a redhead, but I'm not a hothead."

"Patience is a virtue."

"Patience is a virtue I never learned."
