Generally speaking I do things myself because it's cheaper, in that it lets me allocate cash in higher quality versions of things than I would otherwise be able to afford. I grew up pretty poor and that was how my family did things. Car breaks, that's why you buy a Chilton's. Appliance isn't working? You can always order the part for a tenth of what it costs to have the appliance guy tell you what's wrong. AC quit working? Those capacitors are super easy to replace and only cost $7.

Now I could pay people to do more things for me, but it's only under certain circumstances.

Sometimes it just boils down to something my Dad told me underneath a car (or a house maybe) like 30 years ago: "Nobody is gonna care about your shit more than you do."
