Query: Leil Lowndes says, "I'm ashamed of this book"

From The Daily Beast:The veteran life coach and author wrote a 2003 book called Updating!: How to get a man or woman who once seemed out of your league. Now she advocates the opposite. "I wish I hadn't written that book," she tells The Daily Beast. "[Marrying up] is the wrong thing to do. It can really screw up your life. Tell people not to buy that book. I'm ashamed of that book. And you can print that." Her reasoning is based on what she calls the "equity principle of love"--if people don't roughly match in terms of money, status, education, character, personality and, yes, looks, they will struggle to last. "It's mother nature's plan," she says.
