I insource as much as possible. Cooking, lawn care, car repairs, computer work, house work, and other things that I'm probably forgetting that other people outsource. The last time I paid anyone to do anything for me was probably when I got an exhaust leak on my last car welded shut. I don't know how to weld (yet). Coincidentally, my exhaust in my current car got stupid loud starting yesterday afternoon, so it looks like I might be doing that over again.
