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.
Plus, being able to do things yourself means they can get done on your schedule, assuming you actually do them. You're beholden to no one's schedule and energy but your own.
