All of you guys..been in my position:

I'm the same way; pretty much a beginner. I've always been around my dad working on cars and when I started dating my boyfriend 2.5 years ago I got a lot more into actually wanting to learn more. Well I just observe them work on the cars and I ask them to let me help, and they show me how to do things like put on the drive shaft and bolt other random things on, etc. When my parents split I couldn't easily have my car fixed when it wouldn't start and stuff, so I forced myself to stop being scared of working on my own car. I knew the parts of the cars and usually I knew what the problem was, so I forced myself to use Google and watch tutorials. I figured if I break something at least it's my car and I can't be too mad at myself; it's a learning experience. Now I change the oil, build stuff for my car, and I made my own door panels and reupholstered my seats with my sewing machine.
