I'm not making the connections in the article - business success isn't about whether or not you are boring. Neither is happiness. They even said they were happy. Just not motivated. But living a simple and happy life is not a bad thing. Being boring is different than being bored. Enjoying boring hobbies is still enjoying your world. I don't need to entertain others to live a fulfilling life.
So if the author has problems they want to fix with their work or life, by all means fix them. But "being boring" is not a problem in and of itself.
