Start thinking about how to make more advanced tools/frameworks/architectures/whatever-it-is-you-do that allow you to think more and code less.
I wouldn't necessarily recommend spending a year learning to type, but I would definitely recommend writing documentation as a process that will improve your code. Writing proper specifications, proposals, documentation, etc highlights problems amazingly well. I would argue that is what makes you a better coder, more than actually writing code, because explaining how your code works is the best way to see how your code could be improved.
