Joan Rivers was not “a piece of work” when I interviewed her recently. In fact, she was extremely thoughtful, gracious, and thankful. While Joan is known for her work as an actress, comedian, and Celebrity Apprentice winner, she is also a businesswoman. In addition to her show business career, she is active in managing other businesses as well, including her jewelry line which has been on QVC for about 21 years and has been profitable since its inception.
