I found an awesome guitar instruction site that I thought everyone should know about: http://www.guitarmasterclass.net/
It has helped me stay motivated and actually practice the guitar with a purpose. The video lessons are sweet because they break everything down into small chunks. It actually allows you to learn all of those ridiculous solos that you've always wanted to learn! trust me check it out, the instructor Kristofer Dahl is a great teacher and an amazing guitar player, you won't be dissapointed. Also make sure to look at http://www.freelicks.net where he posts a bunch of awesome free lessons. In addition he does some lessons on http://www.ultimate-guitar.com , it's called the shred masterclass series, you should check that out too
