"The only way to do something is to do it. Not to talk about it, not to plan it, but to do it."

"Why do you suppose that, when you are not speaking English, you speak with an accent?"

"I don't know anything, but I do know that everything is interesting if you look at it deeply enough."

"I would rather have questions that can't be answered than answers that can't be questioned."

"I was brought up to believe that the only way to really understand something is to build it."
