Decisions Decisions

I STILL haven't figured out what I wanna do with the rest of my life...I am almost 30 and still haven't found the one passion or commitment that drives me. I have a Bachelor's Degree that I still need to finish, and plan on doing so. There are so many things I should have, and don't. I don't know what I am afraid of, and what holds me back, but the "good life" seems so far away and unattainable. I feel stuck and defeated sometimes, but there are so many people around me that are doing so much better that I feel there's a future for me somewhere...Where do I start? What do I accomplish first?
