A couple of cool Richard Feynman quotes:
"I think I’ve got the right idea, to do crazy things — what other people would consider crazy things. There’s so much fun to be had."
"I have approximate answers and possible beliefs and different degrees of certainty about different things, but I’m not absolutely sure of anything, and many things I don’t know anything about, such as whether it means anything to ask why we’re here, and what the question might mean. I might think about it a little bit, but if I can’t figure it out, then I go on to something else. But I don’t have to know an answer… I don’t feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose, which is the way it really is, as far as I can tell, possibly. It doesn’t frighten me."
Oh, I think I’ll just pick "There’s so much fun to be had" as my quote to live by.
