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.
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.
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.
There's certainly more new SF available than when I started writing. That means there's also more bad SF available. Whether there is also more good is a matter for future historians of the field.
Keep writing. Try to do a little bit every day, even if the result looks like crap. Getting from page four to page five is more important than spending three weeks getting page four perfect.
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.
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.
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.
