Following is a link to a blog written by my cousin, Steven Vrooman. He is a professor of Communications at Texas Lutheran University and author of The Zombie Guide to Public Speaking.
I highly recommend taking a look at his post from December 12th entitled, "I don't know what I want to do with my life." I can relate to this sentiment as one who wants to experience nearly everything before turning back to dust. This outlook, though not for lack of inspiration, can be equally as stifling as not knowing where to start. I find your advice comforting, cuz, "to do what comes next. To find something you hate less than the other things and get ready to shove."

This also brings to mind a recent speech given by comedian Jim Carrey at the 2014 Maharishi University of Management commencement ceremony. In recalling how his father made the safe decision to work as an accountant rather than a comedian, and was eventually fired, Carrey profoundly states, "you can fail at what you don't want, so you might as well take a chance on doing what you love." Wait for it because Carrey is all jokes until this statement about his father at 11:20. After this moment in the speech he has some very insightful things to say about love, fear, the ego, and daring to be seen by the world.
