Truly successful decision-making relies on a balance between deliberate and instinctive thinking.

Once a musician has enough ability to get into a top music school, the thing that distinguishes one performer from another is how hard he or she works. That's it. And what's more, the people at the very top don't work just harder or even much harder than everyone else. They work much, much harder.

It is those who are successful, in other words, who are most likely to be given the kinds of special opportunities that lead to further success. It’s the rich who get the biggest tax breaks.

I don't go to an office, so I write at home. I like to write in the morning, if possible; that's when my mind is freshest. I might write for a couple of hours, and then I head out to have lunch and read the paper. Then I write for a little bit longer if I can, then probably go to the library or make some phone calls. Every day is a little bit different. I'm not highly routinized, so I spend a lot of time wandering around New York City with my laptop in my bag, wondering where I'm going to end up next. It's a fairly idyllic life for someone who likes writing.
