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.

So we had to take this special exam and I flunked it. Erv Upton passed it, and I was scared. I figured if I failed it, I wouldn’t have any chance of getting in. So I failed it beautifully. ... And so it was the first year of this general college, which gave an Associate of Arts degree after two years, and that was expected to be a terminal course. It turned out it wasn’t.

I had set my mind on winning the 1500-meter gold medal in Helsinki in 1952. ... And, it all came disastrously wrong when I came fourth instead of winning. ... Instead of retiring in order to devote myself to medicine, I decided to go on for another two years while I was still a student, working clinically in London, and I did that.

But, tough, I have fallen…flat before. You just get up and dust yourself off.

Get on with it. But make sure you do want to do it. I think that’s the important thing, to be something that you would enjoy. If you only just go into science to get rich or to win gold medals, then I wouldn’t bother, but if you really want to enjoy yourself in the lab, then do it.
