My favorite musicians (Adam Young, a.k.a. Owl City, Aaron Ivey, Family Force 5, to name a few) care about their craft. They experiment; they challenge themselves with new forms and styles. Because of that, I pay attention whenever they produce a new album.
I’m sometimes told my writing style has a distinct sound to it. I suppose it does, but it’s taken years of writing to arrive at it. My style did not emerge fully formed from my head. It took work.
One of my favorite musicians is a perfectionist. I know this because, in my sporadic attempts to be a dedicated fan, I spent some time reading this musician’s comments about one of his albums. He described himself as a perfectionist musician, then stated his work was never finished, only abandoned.
