How/when did you learn what you know??

I feel the same way as the OP. I didn't start working on cars till I was about 20 or so even though I really wanted to. I bought a couple 68 Darts in HS, but had no tools or storage so I had to resell them. Then I joined a club in college where we design and race a small off-roading vehicle and once I felt comfortable with that club I bought another '68 Dart (the one I have now). Just like the OP, I do get very overwhelmed at times and even though people on the forums say it's easy, it just doesn't register that way for me. I've been getting better, however.
