I was wondering what users and instructors here have had formal guitar lessons and who has not?

For formal training I'm interested in serious lessons not I took lessons for two weeks and stopped because my teacher sucked. More along the lines of I've studied for a longer period of time with my teacher and I've learned techniques and theory with them not just jammed and learned songs.

The reason behind it is that I'm finding I don't have much discipline at all and I'm beginning to want to try and find a real life teacher I can go see every week who will challenge me to learn new techniques and theory.

I've gotten a few instructional videos like Rock Discipline by Petrucci, and the Metallica DVDs by Lick Library, and I want to be a good guitarist, but when I look at solos and try to learn them I just get discouraged and then stop trying to learn them because it seems fruitless!

Other thoughts are more than welcomed.
