So much doubt

This isn't what I went to school for, is it? All that hard work, all that money, all that time spent memorizing and writing and reading and reciting has gotten me what? Not very much. I'm not entirely convinced it was worth it. I feel like I've written this too often for it to have meaning anymore, yet the idea continues to run through my mind with the same impact it did that first time I thought it. Where do I go from here?
