Is it really keeping to a "schedule", like something that could be written in a day planner, or is it more along the lines of routine, like say for instance, when you wake up, you have to brush your teeth...then have a bagel (or whatever)...then sit at the computer with coffee...and know that the next thing you will do is shower, and there's no way you can do anything before that (like a chore, or change the routine such as shower first thing, etc) without feeling seriously bothered...
That's why I wind up procrastinating, half the time...its just not on my mental agenda, and I can't allow it to be...
