TV analysts and money managers would have you believe your finances are enormously complicated, and if you don't follow their guidance, you'll end up in the poorhouse. They're wrong. When University of Chicago professor Harold Pollack interviewed Helaine Olen, a financial journalist, he made an offhand suggestion: everything you need to know about managing your money could fit on an index card. To prove his point, he grabbed a 4" x 6" card, scribbled down a list of rules, and posted a picture of the card online. The post went viral. Now Pollack teams up with Olen to explain why the ten simple rules of the index card outperform more complicated financial strategies. Inside is an action plan that works in good times and bad, giving you the tools, knowledge, and confidence to seize control of your financial life.
