In a recent interview with NPR’s 'Newsmakers', Jamie Dimon (CEO of JPMorgan Chase) cautioned against making significant decisions on Fridays, attributing this to decision fatigue that accumulates over the week. He explained that by Friday, cognitive resources are often depleted, leading to rushed decisions without adequate information. Thomas Roulet, a professor at the University of Cambridge, supports Dimon's view, noting that leaders may struggle to process information effectively by the week's end. Dimon also discussed the importance of emotional control in leadership, stating, 'Anger doesn't help,' and shared personal lessons learned over time. He emphasized the significance of having a purpose in life, which can manifest in various roles, including caregiving and community service. Dimon reflected on the quiet heroism of individuals who contribute positively to society, reinforcing the idea that making the world a better place is a vital aspect of one's purpose.
