Anyone can become a better leader, but only through a belief that they can grow, an aspiration to excel, constant self-challenge, the support of others and deliberate practice: designed learning experiences with a specific goal, repeated over time, with feedback from a coach, mentor or other third party, made a daily habit rather than an occasional event. Leadership development is self-development: leaders work through who they are, so the leader reflects on peak experiences, guiding values, the future of the organization, sources of courage and the trustworthiness of their relationships, with even a few minutes of daily reflection improving later performance. Each of the Five Practices becomes destructive in excess (obsession with being a role model, a single vision that blinds, change for its own sake, collaboration used to avoid hard feedback or to dump work, celebration that loses the mission); humility is the antidote to hubris, and leading is doing.
