Great leaders are not simply made by their circumstances or the personal characteristics with which they were born, nor are they lifted into their positions and accomplishments by some sort of superhuman ability to lead. They form themselves by taking their fallible strengths, fusing them with ambition and a sense of greater purpose, augmenting them with the strengths of their team members and refining them as they weather their own personal crises. By doing so, they are then able to rise to the occasion when confronted by larger crises on the world stage.
