Help! I'm just too busy!

With four kids, a part time job, a full time house, home schooling, Boy Scouts, Little League, and hounding, I just can't find the time or the brain power to blog. Oh, and I also knit, crochet, and sew. I sell my items on line and at farmer's markets. I really want to blog though! I see that other moms do it. Any advice out there? Do you jot down ideas during the day, or does it just come to you at the computer? I'd really appreciate your input.
