It's not too big a deal if you don't know what you want to do with it right away. Hell, I'm still not 100% sure what would be ideal for me. Doing the class might help you even if only because it would give you a framework to keep you on track, but that's up to you. As for procrastination, I'm the same way. What works for me is to break things up. Work for some number of minutes, then rest for some number of minutes, and go back and forth in small time chunks.
