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.
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.
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.
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.
