How does change happen? This is one of the ‘great’ questions that people have wrestled with for decades. Although I think this is incredibly complex and that we might never really learn a definitive answer to this question, here is one answer from Robert Kennedy:
“It is from numberless diverse acts of courage and belief that human history is shaped. Each time a man stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring, those ripples build a current that can sweep down the mightiest walls of oppression and resistance.”
-Robert F. Kennedy, 1966
