Tonja, first of all; it sounds like you're doing really well! For so many, the 'Mommy-gig' is the death of their writing pursuits. "I would have been a writer but...", or "When the kids grow up, then maybe I'll...".
You should give yourself a huge pat on the back for still being a part of the game! You write when you can, you read sites like these that are linked to your work. Do you give yourself the credit you deserve for all this?
The hardest thing for nearly all writers, is discipline. It seems that you have it, because you know your writing time is precious and short. Maybe try and develop that a bit more -- try to find a time of day, or certain day of the week, when you'll focus your energy on the writing, and then dedicate yourself to it.
But it sounds like you're doing better than you think.
BRUCE: I'm getting more ideas lately for things to write about but I have a problem with getting distracted. If I can just finish this level on a game I'm playing. If I can finish this movie I started watching last night.
The real problem is I need to commit to sitting down to write more often and I'd like an editor to go over my work. I'm too wordy and I need help getting my point out in a shorter fashion. HELP!
Go Where The River Is Flowing! My new catchphrase!
