Getting inside the mind of a terrorist wasn't difficult at all. Even as children, human beings fabricate elaborate revenge fantasies. We're not a particular species. Check out popular video games.
Writing allows me the time to travel and see the world, which is what I always wanted to do. I'd really like to have been Sir Richard Francis Burton, but it's the wrong century.

I usually do one con a year as a GoH and try to make the World Fantasy Convention for business purposes. Last year I went to a worldcon for the first time in two decades. I may go again this year.
I have a bad tendency to get rapidly bored with my own material, so rewriting is hard for me. I mean, I already know the story and would rather read something new.
I enjoy listening to classical music and heavy metal. I play basketball and try to go diving at least once a year. I don't really have hobbies in the traditional sense... I engage in too many activities already through the actions of my characters.

I see the Jedi mission as giving up a normal life in exchange for protecting the innocent. It's a life of sacrifice. There are rewards, but also a certain degree of sterility.
