It is very cool to see how all the challenges fit together to build the song. This is the most excited I have been about playing in a while. And I am actually attempting skills I have seen other guitarists doing, but did not know how to get there. I was getting too comfortable just playing the same melody from a book over and over and strumming the same chords in the same pattern. This has really challenged me. The hard part is letting go and not trying to perfect the one song.
