Simon Sinek, ethnographer and leadership expert, explains the function of a leader in a group, taking us back to the beginnings of our existence. He believes that the driving force, for most of our actions throughout the day, comes from the release of the 4 “happy” hormones – endorphin, dopamine, serotonin, oxytocin and the “stress” hormone – cortisol. These hormones produce the feelings of happiness, joy, love, contentment, pride, accomplishment etc. Simon calls the dopamine and oxytocin, “the selfish hormones” because they can be induced by solely actions like running or achieving goals. However, through our existence, it has been concluded that we are social animals, and we need the recognition from others. Also, in order to survive we need to stay in a group. As per every naturally formed group, there is an alpha person, chosen to be a leader of that group.
