We’ve always made lists: chore lists, errand lists, to-do lists, projects lists, possible baby-names lists, financial goals lists, Christmas lists — and the lists go on and on. But years ago, when we were “dirt poor,” we started doing something that has stuck with us to help avoid impulsive and costly purchases. It has also helped us to stay focused on what we really want and has given our kids and us great satisfaction. It’s something we call a wish list.
