Art in my world

First, I think I have a different idea about what art is than most people. Being both an art teacher and a illustrator, I find that I have developed an appreciation of many types, levels, and approaches to what we call "artwork". I find, at times, that I struggle to decide what "my" area of expertise is in this life of mine. I draw cartoons, caricatures and illustrations for a variety of clients and then I fall into watercolor for another, then oils, only to find myself working yet another week-end making posters. It all seems like art to me but, is it art to others or just a picture that interests them at the moment.
