Besides many nix computers I also have wife, dog, children, chores, shopping to be done. Unlike when I was young engineer I could stay all night fiddling with bash scripts and environments.
What does your wife, dog, children, chores, and shopping have to do with custom configuration and scripts? Just set up a Git repo online, put your files there, and take a couple of minutes to improve it incrementally when you encounter inconveniences. And just like that, you made your life easier for a marginal effort.
Having a wife increases the opportunity costs of the time you spend on maintaining the scripts and also increases the costs while writing these (when the wife is nagging).
