Michelle Singletary knows how to navigate the some times troublesome waters of finance. She learned how to do so from her grandmother. In her book, “Spend Well, Live Rich: How to Get What You Want with the Money You Have,” she explains how her grandmother, who was on an annual salary that never exceeded $13,000, ended up owning her own home, paying off a car loan, and had a savings account that supplemented her Social Security check and small pension. That early financial education set the tone for Singletary’s “mama knows best” advice–advice that can be found in The Washington Post column, “The Color of Money,” which is now carried in more than 100 newspapers across the country, including, the Atlanta Journal Constitution, Miami Herald, Boston Globe, and Philadelphia Inquirer. Singletary is also a media personality as she has appeared on the “Diane Rehm Show,” “Oprah,” “NBC’s Today Show,” “The Early Show on CBS,” “Nightline,” and CNN.
