Stop writing code.
Stop writing code. Know how to write code. Be good at it. Be very good at it. But don't do it for long. Or else your growth will be stalled. You'll be just a resource. Unless you're Walter Bright or Andrei Alexandrescu and lets face it, most of us are not them or cannot become like them. Most of us are just making minor enhancements, copy-pasting or running behind new languages/frameworks in an attempt to look cool.
