True. I used to change my own oil in my younger days. But frankly I'd rather spend my Saturday afternoons doing something else. So I'll pull into an oil change place during the week and have somebody else do it for about $30 while I catch up on office email in the waiting area. To me the $30 is well worth getting my Saturday afternoon back.
I also have a handyman come by periodically to do odds and ends around the house like touch up paint, put in the screens, hang a wall-mounted TV, etc. All stuff I'm capable of doing myself but I prefer to pay somebody else in exchange for having more time to do other things.
So it's not about being lazy or incapable for many people.
The cost of oil changes by a third party really cheaper than doing it youself.
I used to do all my own auto repairs myself as well. I’m at a place where various physical problems make it more difficult than it should. So I do the unthinkable and take the cars to the shop. I see it not merely a convenience for me, but I’m putting money in a guy’s pocket that has a family at home to support.
The reason to get a good job is so you can pay people to do the stuff you’d rather not.
