I usually write about ordinary people and ordinary things, but Paul Farmer is the least ordinary person I've ever met... He's the leader of a small group of people who hope to cure a sick world, and I hope my book can help in some small way.
I gave up so many things. It wasn't that I was out of control - it was just years of eating anything I wanted. I wouldn't eat a whole pizza, but if I wanted pizza two or three times a week, I didn't think to limit myself. So I just cut out all the stuff that I viewed as unhealthy.
When you're trying to solve a problem on a new product type, you become completely focused on problems that seem a number of steps removed from the main product. That problem solving can appear a little abstract, and it is easy to lose sight of the product.
