Key words - you “feel good” doing them. I’d argue you’ve made an economic trade off.Not really. Sometimes it's nice to accomplish a task yourself and you don't need to run the math vs your hourly wage. Do I want to install insulation or dig post holes myself when I can pay someone else, not really. But change my oil / filters, replace a window, or reside the garage. Yeah, those are tasks I can fill good about spending the odd weekend accomplishing.
FWIW, I still change my own oil and filters because it’s easy and I am sure it will be done right and I won’t get ripped off at the stealership. But - that’s no less an economic trade off than anything else discussed here.
