I did this for ~10 years, and absolutely no regrets, it was a lot of fun and the side projects gave me energy.
Nowadays it's hard though, learning a new language, with a gf and a full-time demanding job, I don't have a lot of time to be tinkering. I do feel a bit sad about this but just assumed it's just life, and cannot imagine with kids how impossible this'd be.
I did look at doing some basic housekeeping with LLMs (updating deps, standardize testing across projects, etc) and realized I have literally 200+ side projects, most of them websites/JS libraries/React libraries. I was a bit baffled, of course 80% of it is trash, but I was kind of amazed at how many things I've actually done.
There’s this special feeling when you can sit down later in the evening to tinker for a couple of hours, or read a challenging/inspiring book in peace.
But when I don’t have time and frankly energy, then I still try to do _some_ minutes of this kind of thing daily.
I feel like there‘s a big difference between 0min and 15min for anything (also includes exercise, meditation etc.), and while it’s great to have more time, there are diminishing returns beyond 30/45min.
