At the end of the day the question comes, what are you doing for the world? You have to try to do something that's going to add something positive.
Turbulence is the most important unsolved problem of classical physics.
I would rather have questions that can't be answered than answers that can't be questioned.
Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough. Work as hard and as much as you want to on the things you like to do the best. Don't think about what you want to be, but what you want to do. Keep up some kind of a minimum with other things so that society doesn't stop you from doing anything at all.
Study hard what interests you the most in the most undisciplined, irreverent and original manner possible.
You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It's their mistake, not my failing.
When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty darn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty - some most unsure, some nearly sure, but none absolutely certain.
As an actor the best thing you have is your imagination. You're not going to have all the experiences, but you draw on the things that you know. So I think you definitely use the things that you're familiar with to your advantage.

The Constitutional framers were peace men; but they preferred revolution to peaceful submission to bondage. They were quiet men; but they did not shrink from agitating against oppression. They showed forbearance; but that they knew its limits. They believed in order; but not in the order of tyranny. With them, nothing was "settled" that was not right. With them, justice, liberty and humanity were "final;" not slavery and oppression.
I cannot tell you how many people, powerful people, come to my studio and they are in tears they are so moved by what they see.
