Bad: My high school programming classes. All through high school (and now college, where I'm actually majoring in Internet Technology) I've never taken two classes on the same programming language. I keep getting shuffled around from language to language, always learning the basics, but never becoming proficient enough to be able to do anything of any real use. What's frustrating about it is that I love programming. I'm good at it. I really am. I have a programmer's mind.
