I pretty much stopped writing code for myself/as a hobby when I started writing code as my day job. There really is something about losing passion for a hobby once it becomes work, at least in my case.
I went from writing my own tricked out Web 2.0 blog, writing my own 6502 NES games, writing myriad utilities and scripts to… remodeling my home, learning how to operate and maintain a pool, work on vehicles, garden and homestead.
I think in hindsight my hobby isn’t programming, it’s learning and I just enjoyed learning programming and kicked out into a good career.
