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 don’t know. That’s a terrible answer I realise, and everyone wants a nice straight forward answer. I think everyone, all scientists, have these kind of wacky ideas along the way, and some of them work and some of them don’t work. And this was one that, you know, came and was successful and went forward, and again it sounds obvious to say we were lucky – but we were lucky, you know, there’s way more ideas fail than ever succeed, and this was one that, you know, we were very excited about at the beginning, we thought it had a very low probability of success, but it took off, and it took off like gangbusters. That was wonderful to see.

I would try to write my war story, whether it was interesting or not, and try to make something out of it. I describe that process a little in the beginning of Slaughterhouse Five; I saw it as starring John Wayne and Frank Sinatra. Finally, a girl called Mary O’Hare, the wife of a friend of mine who’d been there with me, said, “You were just children then. It’s not fair to pretend that you were men like Wayne and Sinatra, and it’s not fair to future generations, because you’re going to make war look good.” That was a very important clue to me.

Day one of my first job out of college, my boss found out that I didn't know how to enter data into Lotus 1-2-3. That's a spreadsheet—ask your parents. His mouth dropped open and he said, ‘I can't believe you got this job without knowing that”—and then walked out of the room. I went home convinced that I was going to be fired. I thought I was terrible at everything… but it turns out I was only terrible at spreadsheets.

I think fear and fear of the unknown and perceived failure is what holds people back. For me, I am more scared of complacency than having something not work out. I'd rather take a leap of faith and fall than stand on the edge forever.

That’s a great question. Coconut oil. ... Everything. You can take a bath with it. You can put it in a smoothie. You can cook vegetables with it. You can actually put it on your skin. I think coconut oil is a cheap miracle buy.
