It's pretty hard to stop learning if you're at all interested in a subject. But goddamn, if programming isn't an endless hole of more and more stuff to learn.
Here's something I've realized about new programmers. They all want to try to trick themselves by shortening variable names. Don't this, kids. Make your variables as descriptive as possible. You get dumber and dumber as you learn more and more, and it becomes impossible to remember or even care what all your shortened variable names meant. Just say what you mean, and don't try to be cute.
