I do this a lot. I started programming from very early age. Ten years later I still have the same excitement when I start coding something. And most of the time, rather than looking at the business aspect of projects, I look at how the project can improve my coding skills. And this makes me reinvent everything. I push myself to study a new language or framework for every other project. Me trying to build new websocket library from scratch to creating a simpler web framework for PHP from scratch (when Laravel already existed) to creating a NodeJS framework from scratch to learning React when I am already very comfortable with Vue are all some examples. There are hundred other instances. Anybody else have this issue? Why am I doing this?
