"Metaphor allows us to explain things to people in indirect ways, sometimes avoiding confrontation, sometimes helping another to see that which she has difficulty understanding.
"Art allows us to focus another's attention on aspects of a feeling or a perception that he might not otherwise see, literally framing the point of interest in a way that it becomes separated from a background of competing ideas of perceptions."
--Daniel Levitin, The World In Six Songs: How the Musical Brain Created Human Nature (2009, p 21).

I strive to be more clear in my communication, to more fully and thoroughly express my observations, my emotions. I strive to use my artistic talent, my creativity, to focus clearly on framing my chosen point of interest, so that my thoughts and my message can be more precisely and openly expressed and voiced.
And,I will do this in my writing, in my music, in my painting, and in all my creations. And, in that work, I will improve and I will be more clear, more expressive, and, ultimately, more creative. After all, I am an artist.
