I just found this site and it looked like just what I'm looking for starting out.

I picked up a cheap acoustic about a month ago and have been fooling around on it since. I have since learned a few random easy songs (Stars Spangled Banner, a really simple version of Fur Elise) and a few riffs (Smoke on the Water, Sunshine of Your Love). I seem to have no musical talent and all I have is repeated, brainless practice. Now I wanna start chords but I'm finding it impossible to get anywhere even close. I've been practicing for more than a week and am not getting any better, at all. Any suggestions?
