How many times have you wasted an hour or two online and then realized you didn't get even one new article written? I know it's happened to me. Yeah, you have to reply to blog comments and check out your friends' articles ... but first things first. Break down your goals into daily to-do lists and add them to your planner. If you're a WAHM, your planner should be chock full of things -- daily chores, menu plans, appointments, kids activities, writing deadlines and the like.
I used the Motivated Moms system for the last few months of 2008 and just purchased the 2009 version to keep me on track for the new year. It rocks!
Here's a sample page of my Motivated Moms 2009 Full Size Planner: (click image to enlarge):

It's basically the Fly Lady house cleaning system broken down into daily checklists, with my self-added writing goals and daily appointments all in one place. If you have trouble balancing it all, resort to this simple checklist system. It rotates your chores for you, incorporating daily, weekly, monthly and seasonal tasks all in one simple planner system.
I'll be relying on my Motivated Moms planner to make sure I keep up with my writing goals for the year and stay on top of the house. I love writing, but I don't love housework. Knowing what I have to do each day simplifies things.
