Wow, it's been a little over two months since I got my first guitar, and I was friggin horrible! I had constant trouble switching to the D-Major and Minor chord from any other chord; it always sounded choppy and clumsy and I damn near gave up. I woke up today and was just messing around playing the Johnny Cash version of "Hurt" and wouldn't you know, it just clicked. I could do it, easily, without even thinking. Just yesterday I was practicing boring repetative chord progressions and thinking "Man, I'm not getting anywhere..."

May not seem like a big deal, but it meant a hell of alot to me...
