Welcome to Kiplinger's My First $1 Million series, in which we hear from people who have made $1 million. They're sharing how they did it and what they're doing with it. This time, we hear from a married 55-year-old attorney in Rhode Island who's retired but working part-time. It took him a while to find his footing, but he credits his mom for providing the foundation that helped him get there. (Happy Mother's Day weekend to all the great moms out there!)
