It's a fine line and I like to walk up and down it a lot. The line between procrastinating and percolating. See, I believe in BIC (Butt in Chair) and I also believe you need to write to be a writer. But I don't write every day. I think every day, despite the amount of laundry and heinie I clean. I get into my WIP's world and walk around. I'm at the stage right now where I can't approach it head on. I can't sit down and write, not yet. I need to think about it.
For example, yesterday I finally cleaned out the tech junk drawer. That hideous repository that all offices have of cables, broken cameras, headphones nobody likes to wear, and old technology. I unwound the tangle of cables and sorted them into piles. Busy hands means a whirring mind for me, so in that time I 'wrote' my opening scene. I discovered the MC's voice (yes, I heard it in my head, you got a problem with that?)
But I haven't run to the computer, not yet. It's a delicate thing with me. I need to 'think' back into that scene and replay it, like a video, in my head. Then I can write it.
If this was three years ago, I'd be berating myself for procrastinating. I'd have good reason to do it, I spent almost ten years 'thinking' about my first book without writing a word. But now that I'm embarking on writing my third book and am querying my second, I think I can trust my process. I know I can do it and I know I won't be afraid. For me, that's what procrastination was, fear of failure.
So, what's your process and how did you come to trust it?
