Science seeks the truth. And it does not discriminate. For better or worse it finds things out. Science is humble. It knows what it knows and it knows what it doesn’t know. It bases its conclusions and beliefs on hard evidence -­- evidence that is constantly updated and upgraded. It doesn’t get offended when new facts come along. It embraces the body of knowledge. It doesn’t hold on to medieval practices because they are tradition.

I've probably done the odd thing. I've probably done more than I would have done and some things you don't say no to. You don't say no to working with "The Simpsons"... the greatest comedy show on television. You mustn't. Even though going to my bad judgment, I remember saying that all I can do is make this show slightly worse.

Daniel Day-Lewis would play me as a baby. He can do anything. Johnny Depp or Brad Pitt are fighting out for me now. And Meryl Streep will play me after the sex change. I haven't told you about that, have I?

Know your limitations and be content with them. Too much ambition results in promotion to a job you can't do.

Why buy a book when you can join a library?
