Book excerpt: You should worry about your legacy later in your career, at the edge of retirement—right? Not according to Robert Galford and Regina Maruca. In Your Leadership Legacy, these authors argue that thinking about your legacy now makes you a better leader today. Based on stories of top leaders who have shaped successful careers, the book explores the art of "legacy thinking," helping you to formulate a legacy that will exert a positive effect on your work immediately. The authors provide a disciplined approach to framing your legacy, as well as shaping it over time. They start with the idea that your legacy is defined by how others approach work and life as a result of having worked with you. They then demonstrate how to assess your current impact on those around you, strengthen that impact, and pass along the best of yourself in the process. While many leaders "find themselves" and hone their work accordingly only after a major life crisis, Your Leadership Legacy enables all leaders to craft their work and build their legacy unburdened by such crises, and to experience personal satisfaction and achievement throughout their working lives.
