Revolutionary rap artist Tupac Shakur was always thinking about the bigger picture - changing the world, making a difference and being straight up about the truth. He had a big heart and he did not care about making music that revolved around money, clothes and cars. Tupac, whose mother was a civil rights Black Panther, had a stronger purpose to help others who were struggling. And although some of his music was dark, most of it was about creating a ripple effect of change. In this powerful clip, Tupac talks about sparking the brain of the person who will change the world. He finishes up by saying "if I keep talking about how dirty this world is, somebody is going to clean it up."
