I kind of know what you mean. Ever since I stopped taking lessons, I haven't really been able to pick with much dexterity. Like, single notes and stuff are fine, but if I'm supposed to do something like fret a chord and only play a couple strings, I usually end up doing a full strum anyway. And also, I've noticed that I can't get into chords as fast as I used to. I used to be able to go from chord to chord pretty lightning-quick, but now I can not.
I guess we just have to keep at 'er, huh?
