If you have some basic skills coding and would like to improve, join an opensource project/community. There will be several opportunities, both small and big, to contribute. The amount of growth you will experience actively trying to solve "the issue at hand", is enormous. The sense of pride when you create something or "fix" something broken is nice added bonus. The same is applicable to almost all other skills, from marketing to video-editing. Become part of a community, contribute. Feel better and make the world a better place. Just fucking do it
