Sometimes, though I really hate to admit it, practicing guitar could be a whole lot easier if we watched TV while doing it. Why? When we first learn something new, it is at the cognitive level. Unless we have Super-Man-esque concentration levels, we need a distraction. Thankfully, there are CSI reruns. After we learn something new on guitar in a lesson, it is not something we need to understand so much as play.
Try this out if you don't believe me:
Try learning two new chord progressions. It could be something easy like say: G-Bminor-A-E (the Bminor is thrown in there because it isn't the most used chord in pop music). Or it could be something more in line with where you are at. Then just sit down on the couch, watch your favorite Indiana Jones movie, and then when it gets to the part where Indiana Jones is punching some evil dude, check on your progress (which is like every three minutes in those movies).
Voila. Watching TV gives your brain a break, and allows your fingers to get more nimble at playing guitar.
