Write a lot of code. Read a lot of code. You can try programming competitions. Typing speed. These are things I did as a fairly junior to intermediate developer. (so the first 10-15 years) Later on it's about knowing what to do, the right approach can be infinitely faster than the wrong approach that doesn't work. EDIT: as someone else said, know your tools, whether it's your IDE, your editor, your debuggers, your compilers, profilers etc.
