Been awhile. But my art life continues. The library is a  good teacher. The business book section has answers. I sell my own art. I do most of it by direct mail and in person. The business part of art life is half of the discipline. My Tools 4 Artists are - carry business cards, send out snailmail news and updates, stay in touch with your art people by letter, Show in a buyer's home, get local press by calling, not email, get sponsors for art projects. Read the Outliers. See my business tips on Facebook.
