It's a terrible thing, I think, in life to wait until you're ready. I have this feeling now that actually no one is ever ready to do anything. There is almost no such thing as ready. There is only now. And you may as well do it now. Generally speaking, now is as good a time as any.

I'm not a religious man... I find I am a fan of science. I believe in science. A humility before the facts. I find that a moving and beautiful thing. And belief in the unknown I find less interesting. I find the known and the knowable interesting enough.

One of the principal goals in my life has been to avoid embarrassing my children by doing the job I do.

I must say, my three are most agreeable children, who do nothing but delight me.
