In fact, what I usually say to people, “Probably some of the most successful scientists are the ones that know how to deal with failure well.” Because it’s easy to feel good when you succeed. That’s an easy thing. But you’re probably going to fail in science a lot more than you succeed, so you really have to learn how to deal with it and not let it beat you.

No, no. Well, you know, biology is such a complex system. It’s totally different from the engineering. We cannot design. Many people tried to find the therapy for cancer, but all failed.

It happens in the course of writing. I can’t go on if it’s not pretty much the way that it should be. Towards the beginning of a book, I will go back to page one every day and rewrite. I’ll start out the day with some marked-up pages that I have marked up the night before, and by the time you get to page, maybe, 270, you are not going back to page 1 necessarily anymore, but you’re going back to page 158 and starting over from there.
