Whenever you take a subject you're obsessed with or that haunts you, and make a movie about it, you're converting it into work units that need to be completed. You gotta turn it into a treatment, a script, a grant application, a bunch of forms to be filled out, a shooting schedule, casting sessions, auditions, shooting, editing, music compositions, the film festival circuit, interviews even. And by the time you've finished the process you're so sick and tired by something that was once very precious to you that you're done with it.
