It's ironic that you were working on a script to solve writer's block, because this whole phenomenon of "immediately after I finished I saw the poor quality of my work and got depressed" you're talking about sounds an awful lot like writer's block. I spent a couple of years in grad school before I decided to quit the field of computational biology. All that learning about DNA analysis was worthless, and I was sad about it. But in the years since then I frequently come back and draw analogies and use the things I learned. Just yesterday I was discussing the problem of developing a map from a large corpus of gps paths and realized, hey this is a lot like shotgun sequencing. A lot of stuff will end up being pretty useful.
