E.T.
I agree with everyone else, set a designated time to write. This is easier said than done and I feel like I end up spending all day on the computer, researching, writing out character analysis, planning out plot lines and then very little writing-- but to me this is all the same thing. I also try and get at least a few pages done every day, even if they get deleted the next day, at least I wrote something. Facebook is a huge distraction, as is Mamapedia, but I bounce back and forth. For me, I also need inspiration and I've always said I have to read what I want to write to be able to write it. So I read, a lot, and after I finish something it gets my brain working and I can focus on my own work again. I am also focused on one project at a time, and that helps focus my energy. Occasionally I'll think of another plot line or scene or something for something I'm not exclusively focused on, and I'll take a moment to jot that down so I don't forget, but it gets saved in its it own folder and I go back to my main body of work. But keep writing!! It will help you be productive and its the only way I stay sane in a world of Thomas, Barbie, playdates and house cleaning.
