University of Chicago professor Harold Pollack studies public health and health policy. He’s also got an unlikely side gig: Money management guru. In his book The Index Card: Why Personal Finance Doesn’t Have to Be Complicated, Pollack breaks down everything you need to know to deal with debt, save more money and get your financial house in order. Boiled down, all of his tips fit onto a single 4x6 index card. 

We talk with Pollack about some key bits of financial advice and hears the very personal story of why he decided to write a book to help people better manage their money.
