how did you learn to work on cars?

My dad sold used cars out of our yard always took me along with him to all the car auctions and started me patching up the ones we brought home to sell when I was about 14 or so .His favorite cars to sell were always mopars. Tha73t was over 40 years ago. I still have some of his tools and several old mopars in the yard. Tried to teach my son the same way. His daily driver is a 73 DART SWINGER.
