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.

They compete for time.

Don't even try to explain the scripts to wife*, try the dog. At least he'll understand it just as much and be enthusiastic to hear it!

*may not be applicable to all wives, ymmv.

I thought my wife latex, she loves me for it :D

I'm saying that makes no sense, as I've wrote in the comment you're replying to.

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).
