"I celebrate when I'm in pain."
I used to use lyrics as my subject lines when I would email my ex-girlfriend, and the above lyric is from a band that's really worth listening to, Sick Puppies. I have several of their videos in my library if you wish to check them out, and you can find their album, "Dressed Up as Life," on Overstock.com and other excellent on-line purchasing sites. (I don't use Amazon, as they censored one of my reviews without cause or follow up, and me ... I don't like to support censorous folks, so there you go.)
I pulled this lyric, because it encapsulates a muse for me. I find I'm my most prolific, I am most called to create ... when I'm in pain.
