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?
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.
