I spend a lot of time fixing things, for myself and others. (Computers, electrical, plumbing, etc). While I learn a lot, I wonder sometimes if it would be better to pay a professional and do something else for which I am more ‘valuable’. Do you do the same, and do you find it worthwhile?
Unless you’re actually using the time that it frees up to make more money, that’s not a useful exercise. If you’re just thinking that you could make more money, but you didn’t actually do it, then you’re just paying to have time to - whatever it is that you do with that time. Which could still be valid, but it’s a different judgment proposition.
