So you have your instrument but…oops, you forgot, you don’t know how to play a lick (in fact you don’t even know what a ‘hammer-on’ is). Maybe music classes are the way to go. The first guitar teacher I had when I was fifteen was a blind dude who checked my fingering technique by putting his hands on mine. It was a little weird at first but helped me learn how to hold my hands right. While it’s true that you only need about five chords for most rock music, learn the basics before you try to get on Conan.
