I just don't know anymore

I'm being overcome with the realization that I don't really know where I stand right now. I've been staring at my homework for well over an hour (it was originally due on Wednesday) and I'm pretty sure that my brain has decided that the semester is over, yet I keep telling myself to keep going. But it's more than that. I feel like I could swing either way in a number of decisions. For example, as I was walking to my room and considering writing a blog entry (instead of doing my homework), I managed to smash my fingers in the door. The result was about 15 seconds of clenched teethed and agony followed by laughter. Should I really be laughing about something like smashing my fingers in the door? Also, a friend of mine has given the sleeping artist inside of me a nudge, and I don't know if I should let that artist wake up or not. I have a history of excelling in artistic pursuits, but I've never really applied myself. Teachers were amazed at my artistic writing at an early age, high school art projects left instructors baffled, and recent exploration into a new instrument leaves me wondering if I have a natural talent for music. I mean, I can whistle pretty good too. ;)
I like where I am, but I don't always see it leading where I believe I need to be. Should I cast off my past and get a clean start, or should I use what I have as a springboard to find my place? Should I strengthen friendships, or be grateful for what I learned and search for new relationships? I'm happy, but at times discontent.
Should I do my homework or waste time? Should I grit and bare some pain, or should I laugh at it? Should I focus more on my textbooks and education, or freedom and art? Should I choose a feeling of accomplishment, or a sense of expression? I'm not 100% sure right now. I can't help but feel that there must be a healthy balance somewhere, but I almost think I need a new source of inspiration to encourage me to try hard enough to fit everything in.
