It can be about any sort of maintenance task that people tend to outsource. Fixing the sink instead of calling a plumber, changing your own oil, weeding the edges of the lawn, running Linux on your home computer. There's a personality type that can really get behind such things as an end to their own, and this book really appeals to them.
Most of us don't want a new hobby of "spend a few hours ever week or so to keep my computer capable of running software", but if you hang around places like this, you'll find that plenty of people do. They can't understand why you wouldn't care enough about your computer to do some basic research into its workings and occasionally recompile the kernel or make a few trivial tweaks to a driver to get it working to your satisfaction.
No amount of "already having a hobby" or "prioritizing for things you care about most" will convince people like the author/protagonist that there's not something fundamentally wrong (but, happily, fixable) with the way you approach life.
So yeah, it's not for you and me. It's for them. And they absolutely love it.
