Simon Sinek has a simple but powerful model for inspirational leadership all starting with a golden circle and the question Why? The author and ethnographer an anthropologist who studies specific human subcultures, speaks on his findings on the most effective method to inspire change. He goes into detail about the parts of the brain that a leader must affect to influence others as well as the type of behavior that inspires others to take action for a cause. Start with the Why is Simon’s main tag line, and is based on the idea that if you can appeal to peoples heart and gut, and make them truly believe what you believe then they will trust and follow you. This is interesting because it gives you a scientific breakdown of the human brain and thinking patterns for decision making. In a culture where being social and outgoing are prized above all else, it can be difficult, even shameful, to be an introvert. But, as Susan Cain argues in this passionate speech on student life, introverts bring extraordinary talents and abilities to the world and should be encouraged and celebrated. Business and entrepreneurship is often thought to be a game played best by the outgoing. However in this passionate case for introverted value, Cain shares that really the best environment for every person to be in are the ones that stimulate their productivity and creativity best. While introverts might brainstorm best in small groups or isolation, it does not matter how they do their best work. Its the quality and contribution of the work brought forth that matters most for all personality types, introverts included. His most famous speech, the Gettysburg Address, was crucial in the time of the Civil War. As president through the speech, he explained why the US needed to fight the Civil War and said that it was to see if the country could survive the turmoil. He made heroes of the fallen soldiers in that war, and empowered citizens to continue what they have started to save the nation and make it great. He served as a role model for generations to come. He has been consistently voted in some polls by academics, politicians, students and civilians alike to be the greatest president of all time. His leadership style proved to be effective and something to follow. He was not authoritative, nor was he democratic, and he wasn’t completely hands-off. He would allow for opinions to flow in and discussion to happen, but when disagreement came, he would show.
