I think I started learning lessons about being a good person long before I ever knew what basketball was. And that starts in the home, it starts with the parental influence.
I was the type of guy that used to get up in the morning and go out and just out run everybody on the field without stretching or warming up or anything.
At the very end of a book I can manage to work for longer stretches, but mostly, making stuff up for three hours, that's enough. I can't do any more. At the end of the day I might tinker with my morning's work and maybe write some again. But I think three hours is fine.
