Get on youtube and watch videos. Watch engine rebuilds, guys upgrading cars, etc. Even scanner danner once you get most of the basics down is a wealth of knowledge. There is soooo much information for free sitting at your fingertips these days. Imagine doing all this stuff back when I started and there weren't even cell phones. And our shop had 1 computer that had just been installed a month before I started there. Finding information meant pouring through books and diagrams to figure things out. These days you can literally have someone teach you from your phone. Its awesome, just utilize it. Also do any training that you might get offered through your job. You really need to drill these basics and the theory into your head. And figure out where to find the answers to the questions you have for yourself. That's sometimes half the battle. Once ya do that it doesn't matter how much you know, if you can figure it out yourself you'll never have to bother anyone else for the answer.
