You called it vision, I call it analyzing what my strengths were. It just so happened there was no market whatsoever for my strength, unless I was interested in becoming a show dancer, for which I tried, but I’m not tall enough. Also, when I auditioned for the Radio City Rockettes, they said, “We love your fouettés, but can’t you smile?” And things of that nature transpired between me and a commercial future. So, I managed to find a way of subsisting in the beginning by doing odd jobs, Kelly Girl temp work, selling perfume at Macy’s, and any and everything to be able to sustain studying and beginning a career with a group of dancers who were willing to devote five years, really, of their lives to me, working very seriously, with complete commitment, for not a penny.

about 95% of the experiments we do are total failures, and that’s because we’re out there on the leading edge of what’s possible, and most of the time it isn’t quite possible.

Well, I'll be honest with you. I was a theoretical physicist but my Ph.D. work was on a problem that was not particularly interesting to me at the time. And I used to subscribe to Scientific American and I found that there were all these wonderful discoveries happening in biology and I also knew that a number of physicists had gone into biology and been successful. So, I decided to switch.

When we started Airbnb, no one wanted to invest. I felt like a failure so many days. It was small, it wasn't growing... A sane person probably would have quit. But we kept going through obscurity, through rejection. We couldn't raise money — but over time, it started growing.

I go back to this idea that I only discovered when I was older. I wish I had known it when I was younger, because I think I missed a lot of observations in life. That is to develop your own philosophy. I always thought philosophy was one of the most useless subjects in the world.

I remember one teacher in particular. I was in a school in the third grade and they were thinking of skipping me, putting me in a higher grade. But then somebody said that would be bad psychologically. So, for that entire year, because I had learned all the lessons that year — the multiplication tables, whatever the reading was — this teacher let me go off by myself and draw pictures. So I had hours and hours of time where I was just left to my own devices, drawing pictures. And she would encourage me. That was a wonderful period in my life. I mean, I didn’t become an artist, but somebody let me do something I loved. What a luxury, to do something you love to do. I would still like to have that luxury, to be able to just sit and draw for hours and hours and hours. In a way, that’s what I do as a writer. I just sit by myself, being in my own mind, not being directed at what I should be doing moment-by-moment, not having a clear plan set out by anybody and just letting imagination enter into the blank page. So in that respect, I can thank Miss Grudoff of the third grade for allowing me that.
