“I have a theory that selflessness and bravery aren't all that different.”
“I don't have any theories-- all I have are the facts.”
“In theory, there is no difference between theory and practice. But in practice, there is.”
“Reward theory. Some people just aren't worth your tears.”
“The most self-serving thing one can do is live their life selflessly. Selflessly give your experience. Selflessly give your knowledge. Selflessly give your time. Selflessly give whatever it is you have to give. And the world will rise to meet you.”
“Personally, I don't deal much in theory. I have to deal with the facts. And on the basis of facts, I don't see much difference in the behavior of men and women.”
