Jonathan Youshaei delivered the commencement address at Deerfield High School in 2009, a speech that has since been celebrated as one of the most memorable high school graduation speeches ever given. His central metaphor came from an unlikely source: a calculus textbook. While checking the answer to an odd-numbered problem, he saw the fraction 2/7ths and realized it perfectly described how most people live their lives. The '2/7ths' concept captured something that resonated deeply with his classmates and with millions who later watched the speech online. Youshaei argued that while blood moves through our veins and oxygen flows through our lungs on weekdays just as it does on weekends, we are not truly the same. During those five weekdays, we operate on autopilot, merely enduring until the weekend arrives. His prescription for becoming '7/7ths people' — whole people who fully inhabit every day — was to take risks, shed the fear of failure, chase dreams, and spend more time with one another.
