The difference between what we are in the moment, and what we can be is the source our of striving and inspiration. Those things and, more importantly, those who drive us to be more than we are — they build our art and our selves from the questions they create.
Some create their questions by simply asking, directly. From others, questions condense into being through their very existence or way of life. And it is our perception of these questions, as artists, our response, that is the seed from which inspired art grows.
My wife and I just finished seeing the highly enjoyable film "Words and Pictures." We both would recommend it highly to anyone who loves words, pictures, or the human condition. It's is all about the difference between what the artist is and what the artist can be.
