How much research I have to do depends on the nature of the story. For fantasy, none at all.

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.

Don't try to write to the trend of the moment.

I hear entire symphonies, oratorios, in my head, but I can't write a note.

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.

In loquaciousness lay insanity.

Where lies the line between sorcery and science? It is only a matter of terminology, my friend.
