Find a teacher. You can be in the same room as the best guitar player of your area for the same price as a movie show (with popcorn and soft drink), and he'll tell you what to do. I have worked on my own for years before I went to a teacher, and dude, when I saw one, my playing skyrocketed. All those things I just felt, he put words on them. All the techniques I thought I had found, he had mastered, and he showed me how to expand them. All those styles I thought sucked, he showed me, and I started enjoying them.

If you think a guitar lesson is boring, try it out. If the guy is a decent teacher, he'll give you a free tryout... Go for it (and if there's a lot of guitar teachers in your area, you can have a lot of free try outs...) Also, see the best working guitarists in your area, find out who their teacher is or was. The working guitarists aren't the best guitarists, nor are they the best teachers in your area. So find those guys, and stick to them. Even the best have teachers (some pros sometimes come to see me to learn a new scale, or understand a riff they have written, to teach it to their drummers for example)
