Programming

Find a problem that you really want to solve, and learn a programming language to solve it. There is absolutely no point in saying "I want to learn programming", then sitting down with a book to read about programming, and expect that you will learn programming that way. It will not happen. The only way to learn programming is to program, a lot.
