First: I have to give credit to my high school CS teacher. She gave us a good grounding in computer theory about: pointers, memory organization, and algorithms.

Second: Second I just read the fucking manual. Then programmed a LOT more than people who didn't get good. Hundreds of hours during college, thousands since then. I got style information from reading other peoples code and also learned about how not to code by reading other peoples code. Ever buy a book that proclaims to teach you X, but actually teaches you a proprietary wrapper they wrote for X that has a shitty license? Fuck those people. Anyway, when internet sharing became more of a thing I started watching videos by experts and reading articles. And now I learn from people here as well. Never stop learning and always RTFM.
