Throughout history, change has been led by people who’ve responded to the deepest and most universal impulse to improve the life of their fellow human beings. They are the ones that felt the calling, responded to the need of the time, and led the way. They spoke for the least well off, the downtrodden, those who suffered from afflictions, such as disease, and those who were abused by the people how had power over them. Every progressive step, and the overthrowing of old orders and paradigms has required the courage, passion, and commitment of great leaders. They are the ones that saw what must be done, who felt righteous anger over injustice and inequity and took up the cause and led the way. They used their voices, dedicated their lives, and gave what they had to work for the betterment of their fellow human beings. The great social, economic, and cultural revolutions, have come about because of these leaders.
