I think we forget, when we're really stressed and doing a lot of things at once and so busy we can hardly see straight, to take breaks and relax a bit. I also think that we forget when we're taking a lot of breaks and relaxing a lot to get off our asses and start doing the work we need to do. The only thing good about a standard job is that when you have to get to work, you have to go. There are set times and set schedules and all of that. When you're working alone, or doing a project when you don't have a "normal" job, you have to be the voice in your head that makes you move.
