For me, it was all about priorities. When I was writing my first book, I got up at five-thirty every morning to write before work, and sat down at my computer almost as soon as I got home. I didn't cook, I didn't watch TV and I certainly didn't do housework. I was completely selfish. Ian Rankin's wife has recently said that he almost reverts to his student days when he's working on a novel and I can understand why. The problem is that most of us can't be that self-indulgent; babies get really cranky if you ignore them, I've found.
My baby is one year old today. In the past year, I've suffered from the kind of sleep-deprivation that torture specialists can only dream of. I've had zero time to write. And yet, I've still produced five books. My secret once again was prioritising - instead of slumping in front of the TV at the end of the day, I spent every non-baby filled moment writing. I did my best to ignore the dirty dishes. Slowly, the stories reached their endings, because it was important to me that they did.
So the next time you think you don't have time to write, remind yourself that writing is important to you and snatch back as much time as you can to devote to it. Reality will always be there waiting once you've finished. And if you're really lucky, someone else will have walked the dog.
