how did you learn to work on cars?

I grew up around cars and car shows. I dreamed my whole childhood life of having muscle cars. My first car was a 73 340 Road Runner. I had no money and could not afford to pay people to work on stuff. So trial and error. I also read hot rod , car craft, then mopar mags . I still have car mags from the 70's when I was a kid. I still can't afford to pay others to work on my cars . So I will continue to trial and error !
