For me something that sparked a lot of growth with my playing was moving from open chords to learning barre chords. That opened my eyes to a whole new world of playing guitar, with finding out how many different places and ways I could play a chord, and really learning the fretboard. My guitar teacher convinced me that a great way to learn barre chords was to learn blues. I told him that I really didn't want to play blues and I'd never really listened to it. He gave me a SRV tape to take home that week, and from then on I've loved blues. As I tried to learn the blues songs, it forced me to practice those barre chords that I never could get right, and it helped me grow a lot. Good luck, man. You can DO IT!!!
