I am a huge fan of Hugh MacLeod. Actually, many days I catch myself thinking< "um, today's art and message. is barely above average." Then I remind myself to change my attitude. This guy creates art every single day. And all of his art has a message that he cares about. How many humans on earth can say that? He also gives it away for free. He is a very inspriational man to learn from, regardless of your career. Hugh does lots of the are for Seth Godin's books.
