My father was like me - very handy and even if he had no formal training, could look at something and figure out how to fix it or make it better. Thing is, my folks divorced when I was 5 and my mother moved me 1000 miles away. My step dad was the opposite, the kind of guy who figures his expertise lay elsewhere so he would do what he did best to earn the money to pay others to fix or build things for him. But I grew up like my father, not like my step dad, despite not being in an environment where it was encouraged or even where there was an example. I got in trouble a lot when I would get a new toy and within hours be more interested in taking it apart to see how it works than in playing with it. Later in life when my car was up on jack stands in the back yard while I rebuilt my engine, the only encouragement I got was to get a job so I could hire someone to fix it and get it out of his back yard.
And frankly, while I inherited the ability and desire to do things myself, I was taught that sometimes you should apply your time elsewhere and use the fruits of that time to pay someone to do things you could do (but maybe shouldn't or are a waste of your time). I now use my abilities to do things I enjoy doing, and spend the money to have things done that I have no desire to do. Nature vs nurture seemed to work out for me in that regard, at least in my opinion..
