“Laugh at yourself, but don’t ever aim your doubt at yourself.”

It’s really clear to me that you can’t hang onto something longer than its time. Ideas lose certain freshness, ideas have a shelf life, and sometimes they have to be replaced by other ideas.

[You have to be] willing to be changed by the person you’re listening to, where you’re not just waiting for a pause so you can say your thing, but you’re actually letting them have an effect on you if they can.

I have a final word of advice to our students. If you work very, very hard, this is the kind of actor, writer and director you may turn out to be, and if you work extra hard, this is the kind of person you may turn out to be.

I play tennis non-obsessively. I seem to beat people I play a lot or half the time, so I guess I gravitate to people who are as bad as I am.

I’m in this wonderful position where I can do what interests me. And whatever comes along that interests me, I do. The rest of the time I bother scientists about communicating.

Whenever you wonder about yourself, look up at the stars swirling around in the heavens and just realize how tiny and puny they are.

Be as smart as you can, but remember that it is always better to be wise than to be smart.

It’s too bad I’m not as wonderful a person as people say I am, because the world could use a few people like that.

It’s nice to have more time to work on the character, and to have big scenes to play. But if there’s something playable there, and if it’s interesting to do, then that’s nice.

I’m most at home on the stage. I was carried onstage for the first time when I was six months old.

It’s not an epitaph. I felt I could look back at my life and get a good story out of it. It’s a picture of somebody trying to figure things out.

Selling out was frowned on, whereas now you can major in it at business school.

They wont all lie to you but a lot of them will. And itll be the easiest lie they ever had to tell to get your votes.

I really don’t like plays or movies that service propaganda.

Life is great-I wouldn’t know what I’d do without it.

I let a tarantula walk across my hand, and I ate rat soup.

When you start doubting, your mind will start to believe that you will never succeed.

If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.

The dreams we imagine when we are asleep should not in any way make us doubt the truth of the thoughts we have when we are awake.

The first precept was never to accept a thing as true until I knew it as such without a single doubt

For I found myself embarrassed with so many doubts and errors that it seemed to me that the effort to instruct myself had no effect other than the increasing discovery of my own ignorance

Will you tell yourself it’s not true, when those around you all doubt? Will you believe in the power? Cast your net, pay your debt and to yourself be devout.

I doubt, therefore I think, therefore I am.

But what then am I? A thing that thinks. What is that? A thing that doubts, understand, affirms, denies, wills, refuses, and that also imagines and senses.
