How/when did you learn what you know??

Don't loose confidence! I started learning about two years ago at 21 when my cavalier lost a belt due to a bad water pump bearing which had the pulley wobbling. I didn't even know how to change a spark plug or oil back then. I couldn't afford to have it fixed at the time so after buying some $10 wrenches and reading I fixed it and haven't stopped since. Now I've rebuilt a 360, A904 and have done a bunch of repair work on my cars as well as my family's. I never knew car guys or had a dad who knew cars, I've just read a bunch on here along with a couple books and other web sites.
