What to do?

I have reached a sort of existential crisis, in which I am at a loss as to what to make of my life. I don't want to teach High School English forever, but I don't know hos to replace that income. I lack the self-will to pick a course of action and stick with it. I don't know what to do for work this summer, whether to be a personal trainer at the gym, work for the Forest Service fighting wild fires, or apply for grants to study the humanities far away. Long term, I don't know if I want to be a novelist, short story author, journalist, audio producer (NPR-type stuff), or a director of documentaries. (That last one I just kind of threw in. I don't see myself behind a camera.) I am at the same crossroad I have been standing at for the last nine years. Am I too afraid to take a step? Perhaps I am waiting for a sign from heaven, a voice from above to tell me what to do. Maybe this is a time of preparation.
