I don't know if proud is the right word, but I am somebody who does not, on the whole, have the highest regard for my own stuff in that when I look all I get to see are the flaws.
At some point, I had to make a decision: I could practice more and become a really great guitar player or I could work on writing better songs. There are only so many hours in the day, and I found writing songs more fulfilling than working on becoming this virtuoso guitar player.
