I was always telling stories to my little brothers, and my favorite way to put myself to sleep is still to try to unknot a difficult plot problem. Ten-one I'll fall asleep at the most interesting part...
I dabbled in writing when I was young, but I got put off when my parents thought I was only doing so to copy my older brother (also a writer... though he has since rather dropped his novel). I was always trying to emulate him, and wile what they were trying to say was that it was okay for me to do my own thing, the comment did nothing for my self esteem.
After that, my next foray into the world of writing was a short story competition in my early teens. I got an honorable mention. I then played around with short stories for a few years before settling down and writing my first novel. I don't know _why_, it seemed like a good idea at the time.
Since then, I've become an addict. I carry a notepad wherever I go, and I just can't stop!
But looking back, I think I've always looked at things and tried to see the story behind them. It was just waiting to get out.
