If self taught, did you set up any sort of curriculum for yourself or have you just worked on random things each time you practice?
My mom "made" me take piano as a kid .... something I hated at the time but have come to appreciate over the years because I learned how to read and understand music theory. My dad wanted me to take on guitar so he learned along with me. He helped me get started with basic chords. Then I was drawn to singer-songwriters who finger picked so I bought albums and made these folks play the songs over and over again until I could figure out how to do this thing (this was a great school to learn in because I could play by ear and didn't need too much help to figure things out; providentially, there was a guy across the street who was an advanced player and could show me a thing or two when I got stuck). This was sort of my early "curriculum" if you will.
Once I got into high school, it was band after band, Bluegrass, Gospel, Rock, anywhere they'd take me.
My first bonafide formal lessons came in college. This opened up a lot of information to me about how to do things right (it was also at times a humbling experience); these lessons exentuated and expanded my playing and helped me understand better how to be a good guitar player
I'd say the 2 most important aspects of my journey were playing with the albums and playing in bands. The albums exposed me to advanced artists and their approach to playing and the band settings taught me how to be tasteful in my playing (as someone put it "when to play and when not to play; the latter being more important than the former"). Good bands should always challenge and stretch you as a player.
2 tips I'd give to anyone learning guitar: 1) Be purposeful (and realistic) in your practice and goals (something as simple as "I'm going to learn this song today/this week" can be sufficient) 2) Also have times when your only purpose is to enjoy expressing yourself through the instrument (this will help you remember why you took on the guitar in the first place)
