Joy Mangano’s “divorced-Mom-to-riches” story didn’t begin with a mop, but years earlier with a fluorescent pet collar, which was one product idea that got away from her.  This piece in Investors Business Daily offers a quick overview of Mangano’s meteoric rise; her company — Ingenious Designs — today brings HSN some $150 million in sales annually.  One also comes away with the notion that Mangano doesn’t irritate interviewers or readers with false modesty.  “I don’t know of anyone else who has withstood the test of time as myself, barring celebrities, that create and endorse products,” she said.  Investors Business Daily Jul. 19, 2010
