People who are able to strengthen themselves, stand tall among their contemporaries and become the path-breakers for an entire generation. Leaders are flawless; this couldn't be further away from the truth. The fact is that these are people who have suffered hardships from an early stage of their life, and their zeal to face the adversities, and get on with life is what makes them special. Take Winston Churchill for an example -- a man leading a country with its back against the walls and motivating his countrymen to unite against Nazi barbarism in World War II. This great leader of men, suffered from bipolar disorder. As psychiatrist and historian Anthony Storr puts it, "Had he been a stable and equable man, he could never have inspired the nation. In 1940, when all the odds were against Britain, a leader of sober judgment might well have concluded that we were finished."
Leaders have certain characteristics that distinguish them from the crowd. In today's fiercely-competitive scenario, the rules of leadership might have changed a bit, but at the core of it lies the same good ol' die-hard spirit and the piquant conviction in one's abilities.
