It is very easy to be a successful leader. All you need is the charisma of a hero; the wisdom of a philosopher; the vision of a seer; the interpersonal skills of a diplomat; the memory of an elephant; the stamina and fitness of an athlete; the integrity of a judge; the presentation skills of an actor; the humility of a saint; the confidence of a politician . . . One way to find out the secret of successful leadership is to ask great leaders what they think are the most important things that they do in their own life that have led to their success.
