I frequently counsel people who are getting frustrated about an edit war to think about someone who lives without clean drinking water, without any proper means of education, and how our work might someday help that person. It puts flamewars into some perspective, I think.
I continue to evolve as a human, I see things differently everyday so it's sure my songs will continue to change and it's a really good thing. It's nice to listen to my music and remember why I made it.
