In this brief but significant book, the authors, a grandfather-grandson team, explore how using positive psychology in everyday interactions can dramatically change our lives. Clifton (coauthor of Now, Discover Your Strengths) and Rath suggest that we all have a bucket within us that needs to be filled with positive experiences, such as recognition or praise. When we're negative toward others, we use a dipper to remove from their buckets and diminish their positive outlook. When we treat others in a positive manner, we fill not only their buckets but ours as well. The authors illustrate how this principle works in the areas of business and management, marriage and other personal relationships and in parenting through studies covering a 40-year span, many in association with the Gallup Poll. While acknowledging that most lives have their share of misfortune, the authors also make clear that how misfortune affects individuals depends largely on their level of positive energy and confidence. The authors also underscore that our human interactions provide most of the joys or disappointments we receive from life.
