I think I actually read somewhere that it takes 21 days to form a habit, or to get something embedded into your daily routine. So start with that goal - try to hit that 21 day mark.
Since I do almost all of my running in the early morning, I remember a time last year when my wife was out of town and I had to stay home with my three kids, I was a nervous wreck until I was able to get my run in for the day. (Kind of sad, really...but that seems to be the nature of the beast.)
i'm going to have to check out better off dead!
