Life's Calling?

Does anybody ever wake up every day and wonder where their life is going to take them next? I have this feeling every single day at one point throughout the day and I always have to sit back and wonder what my calling is.

I don't have the best feeling about working 9-5 my entire life. Even if you guys don't believe it, I feel I am too creative to be droning away mindlessly on a computer for hours at a time wasting my life away. I want to become more constructive, in whatever way it might be. I just don't know where to head, or how to become what I feel one day I am destined to be. For some reason music seems so natural for me, but I don't think i'm cut out for it. What to do?
