Without practice I can't improve and the practice won't pay off if I don't stick with it. To move forward everyone must practice, some more than others. In my case, a lot more. I and you and everyone need to prioritize...make and take the time or give up the dream. Good luck...stick with it and you [U]will[/U] improve.
And don't give short shrift to Level 2...I think the GT course is well thought out and organized...and necessary to those that don't already know the material/have the skills. Take another look at the syllabus, http://www.guitartricks.com/course.php?input=2 ...there's a whole lot more than "music theory."

"It takes a lot of devotion and work, or maybe I should say play, because if you love it, that's what it amounts to. I haven't found any shortcuts, and I've been looking for a long time."
