Think of great business leaders, and Henry Ford, Madame C.J. Walker, Andrew Carnegie, Estée Lauder and Steve Jobs may come to mind. Regardless of when they rose to prominence, all were not only effective leaders but visionaries and disruptors whose innovative ideas took their companies to new levels and defined their respective industries. When considering the accomplishments of luminaries who exemplify effective leadership, what I find interesting is that beyond the obvious (intelligence, discipline, work ethic), certain characteristics span culture, industries, and even time.
