Obsession led me to write. It's been that way with every book I've ever written. I become completely consumed by a theme, by characters, by a desire to meet a challenge.

If you want to be a writer, write. Write and write and write. If you stop, start again. Save everything that you write. If you feel blocked, write through it until you feel your creative juices flowing again. Write. Writing is what makes a writer, nothing more and nothing less.
