I bet that most writers started writing because there was just this story that wouldn’t leave them alone. It’s like an itch you need to scratch, and your brain’s obsession for a while.
Personally, that’s how it all began. I read a teacher/student romance and started imagining one vampiric style. Soon enough, I was obsessed with the storyline and I had to write it down to get it out of my system.
How was it for you?
