If it's not going to be a quick or easy fix, I then do the calculation of whether or not I want to trade time that I would normally spend on myself or my family for the project. These days there aren't many things that meet that bar. I guess I would frame it as "spend your time wisely because you are rapidly running out of it".
My dad died a few years ago and I've never once wished he had spent more time working on stuff around the house. We would occasionally get in the car and drive somewhere inconsequential talking the entire time. That's what I wish I had more of. All the other stuff I can get from YouTube.
With my kids (who are in college now), there's no way they are going to sit around while I try to fix the sink. If I want to spend time with them, I have to give some consideration to their preferences.
Completely agree! The number of people I know who I think would struggle to know whether to hold the plastic or metal end of a screwdriver is depressing to me. I want my kids to grow up with a basic knowledge of mechanics, mechanisms, repairs/maintenance, and experience the world as things that can mostly be understood (and created) rather than things that are conceived and made by others and merely consumed by "normal people".
It also has saved a fair amount of money over the years, but the mindset is more important to show my family than the dollars.
