When leaders take on a new assignment or role, they replace the leader that came before them. While some prior leaders retire or move to their next assignment after a successful run, in many cases, leaders supplant a predecessor who was not up to the job. Following an ineffective leader and leading a team that has not proven successful in the past requires an optimistic strategic message: “The past has been good. The future will be great.”
Reminds me of Dale Carnegie's "Don't criticize, condemn, or complain' and Admired Leadership's "Fast transitions make for better relationships." Both of these behaviors help me from putting my foot in my mouth almost daily. One behavior that helps me manage this is to think about what I am doing in my job today and how my future replacement would complain, condemn, or criticize it and then make adjustments accordingly.
