When I wanted to learn about racing cars, I literally went and volunteered with any shop or team that would put up with me. Swept floors, went and got lunch, held this and toted that. Little by little my knowledge and skills grew, and I was actually paid to show up. I believe that to be really good at something you have to suffer for your art, and I went to where the best were, and learned from them. Sometimes that meant working night jobs so I would be free during the day, sometimes that meant working for almost nothing, but I learned more about my craft than any 10 of my peers, and thats no lie. Without bragging, there si nothing I cannot do with a race car, nor any kind of race car- be it Porsche (my actual background) Mazda, GM, road race, drag race, dirt, off-raod- doesnt matter I can take a pile of tubes and some parts and turn it into a competitive car. Most of the true masters of thier craft- be it cars or guns or whatever, learned first, opened business later.
