"The Second Mountain" is a concept introduced by author David Brooks in his book of the same name. It describes a journey of personal growth and fulfillment that occurs after achieving success in one's career or personal life, often referred to as the "first mountain." This second phase emphasizes deeper values, such as community, relationships, and purpose. In this framework, individuals often face challenges that lead them to reassess their priorities and seek a more meaningful existence. The second mountain represents a shift from self-centered ambitions to a focus on serving others and contributing to the greater good.
