Hmm, well I suppose some would say they simply "don't have one"(the schedule I mean :wink

. But what you could try doing is instead of bothering to make a schedule, or trying to give your attention to many things at once, why not do a step-by-step approach to things? Some things, such as school, are something you can't really set aside for later, but music videos are something else. You can either try and spend a couple hours a day working on a vid, or crunch it down to work on for most of your weekend, or whenever you'd have a decent amount of free time.
We all lead busy lives, and making music vids should be a fun hobby, not a relentless chore. imo you should prioritize. Spend most of your time on the most important things. And when you feel like you're getting overloaded with work, take a breather or two. Also, if you divided up all your time among school, work, and amv's, you'd have little time for anything else! Put some variety in your daily life by
not having a schedule consisting of just three or four tasks. Hope that helps 8)
