how did you learn to work on cars?

I started pumpin gas and changin oil at the gas station up the street where I grew up. It progressed into settin toe on cars, doin brake jobs and anything else I could figure out how to do. Although there was a fella there, he was not a mechanic. All he did was make me do everything. I pretty much figured it out myself. That was in 1974. It was kinda a downhill coast from there. lol
