Journals and time scheduling are great ways to achieve goals...
but...
why do you feel that you have to finish, be productive, accomplish something in your "free" time? If you're not enjoying the process, why do it? If you are enjoying the process, why do you have to get yourself motivated to do it? Is it more a matter of carving out a piece of time that you can use for something you enjoy (that's a good thing), or is it putting yourself on a schedule to "accomplish" something (which may not be such a good thing)? Don't get me wrong, I've always been on the "I have to accomplish something" bandwagon, but I'm wondering it that's the best place to be all the time.
