Rick Rubin, who has worked with a who’s who of successful artists, agrees, writing, “How shall we measure success? It isn’t popularity, money, or critical esteem. Success occurs in the privacy of the soul. It comes in the moment you decide to release the work before exposure to a single opinion. When you’ve done all you can to bring out the work’s greatest potential. When you’re pleased and ready to let go. Success has nothing to do with variables outside yourself.”
