Mid-mid-life Crisis

I wonder what it is I want to do with myself. Before this month is over I will be 20 years old. Chances are I'm about a quarter through my life. I think I now understand when people go through a mid-life crisis. I used to think, if these people are freaking out about being old, why don't they use what time they still have left to accomplish something with their lives. Make a lasting impression upon the world. But even if one gets over the crippling realization that no one or no thing will be remembered forever and that the entire concept of Earth could be wiped away at any moment in one big mushroom cloud, there still lies the fact that in the grand scheme of the universe, nothing that anyone ever does will matter. Even if someone tears this dimension to nothing and the mere idea that anything existed ceases to exist, the universe certainly won't care. I could discover immortality or kill all life and what would it matter either way.
So if I'm not going to spend my life trying to be something significant then I think all I want from life is job satisfaction. But before I can do that I need to figure out what the hell kind of job would satisfy me that I have some sort of chance of getting. I'd love to spend my time sitting around and writing short stories but so do a lot of other people and the world will only pay so many people to live like that. A couple of weeks ago I emailed the Travel Channel to pitch an idea for a show. I'm thinking of sending one to the Food Network, too. I enjoy college to a point but I feel like I need to start making as many attempts at finding a way to get through my life, that won't drive me insane, as I possibly can. I'm starting to get desperate.
