When I was four, I was in a bad car accident and started having nightmares. My mom tried everything to get me back to sleep. She finally came up with the idea of having me "write" my own stories inside my head. Her thought was they would lull me off to dreamland. I clearly remember the first one involved whales swimming on the bedroom walls, and me riding the waves on top.
This led to a lifetime of making up stories. In my early teens I wrote plays that the neighborhood kids put on. In high school I wrote for the school paper. As an adult, I used to make up all kinds of stories to entertain my elderly clients. You could say I've been training for this writing gig my whole life!
Of course, writing a book is a lot more involved. I still play with the plot each night as I drift off to sleep. Sometimes I wake up and have to furiously write down notes with a flashlight, lest I forget. Other times I can't sleep at all, because the ideas are coming so fast.
My point is simple. It really doesn't matter how you get here. If you're a writer, embrace it, and keep plugging away. If you find yourself getting stuck, I highly recommend a ride on a big childhood whale to get those creative waves flowing again.
Happy mother's day, Mom. Miss you, lady!!
