Living gives you a better understanding of life. I would hope that my characters have become deeper and more rounded personalities. Wider travels have given me considerably greater insight into how cultural differences affect not only people, but politics and art.
Besides the mistakes that are pointed out, I love the way readers become involved with the characters. When readers start asking about character motivations instead of concentrating on the special effects, it means you're connecting with them on a personal level.
Growing up, I never gave a thought to being a writer. All I ever wanted to be was a traveler and explorer. Science-fiction allowed me to go places that were otherwise inaccessible, which is why I started reading it.
Advances have fallen, generally, for everything except the biggest potential bestsellers. Given all the changes, both economic and technological, SF hasn't done too badly.
We're all nothing but unified arrangements of atoms and particles, drifting around, enjoying consciousness every now and then for a second or so before splitting up to become bits and pieces of trees and stars and french fries.
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.
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.
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 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 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.
