crap or get off the pot?

Um, yeah, so Rosa and I are supposed to be signing up for classes this semester..."Just some crap class so we can register before all the good classes are gone next semester." But, alas, I'm doing everything but. I've kinda lost my school mojo for the moment...one more commitment, in a weedy field of commitments...then there is the whole, "ugh, nothing is sparking my interest." Someone have a flint and steel I could borrow?
This goes back to my habit of spreading myself too thin...generally with things that don't really inspire me, or bring me joy...although for the most part, I would have to say that, other than work, most of my major undertakings right now are feeding my soul. However, I know that some further study would do that as well, the question is "what study?" Certainly I have some ideas, which aren't possible at the schools available to me at the moment, so how to make do?
Maybe I should sign up for the creative writing class so I'll get off my ass and have to recall how to construct proper sentences.
