Well, many. I think Steinbeck, for example, was one of my favorites, Somerset Maugham, Hemingway. Quite a few.

The Fountainhead , I think, pretty much saved me in the initial years of Teach For America. I loved that book, but I’m not sure books were the seminal thing that guided my path. ... I think it was sort of about “the creator against the world,” and I was probably feeling at that point that I was up against lots of boulders, to pull off the big idea of Teach For America.

I remember reading The Making of a Surgeon when I was in probably about the sixth or seventh grade. And that was a book that kind of got me focused, I think, on the career path. And I remember, one thing in there I still remember is that you can always tell you’ve really arrived as a surgeon when the nurses in the hospital ask you to be their physician.

I fell in love with the stories by William Beebe, who was an ocean explorer. He discussed what it was like to go down inside a submersible, and peer out of a port hole and see beautiful, luminescent fish, with lights down the side like ocean liners. Bizarre creatures of the sort that you just don’t see walking down the street, or going into the forest, or even looking around in shallow water.

And maybe it’s unfair to use a book. So $100.00 or less? I think one of the best values you can get for $100.00 is a good axe.
