Tim, you go, Boy. I have long said what the world needs is more Science Fiction writers. Almost any Scientist you talk to or see interviewed, when asked the question, "How did you become interested in Science?", will respond. "When I was a kid, I read this book..."
One piece of advice; Read, Read, Read. The works of other successful Sci-Fi writers. Start with this, by Harlan Ellison - "I Have No Mouth and I Must Scream".

All the best!
