When I was 12 I worked weekends at my uncles used car lot selling trucks. Answering phones, washing/cleaning cabs, clearing parts for paint with angle grinder, populating bill of sales, researching competing offers in classifieds, learning mechanics. Hell, I even dug out a shallow trench for a telephone cable, that one took me two weeks :)
