Kordestani saved his most memorable insight for his closing. He told the story of visiting his son's second-grade classroom, where the teacher, Mrs. Woodbridge, shared a philosophy drawn from lessons collected from five-year-olds to ninety-five-year-olds. Sitting at his son's tiny desk, Kordestani learned a lesson that he said summed up everything he had told the graduates that day. This simple wisdom—that small decisions call for rational analysis while life's biggest choices require listening to your heart—perfectly encapsulated Kordestani's own journey. He had followed his heart when he left a lucrative investment banking offer to join a startup. He had followed his heart when he chose Google over safer career options. Each time, the rational calculation pointed one way, but his instincts pointed another—and his instincts proved right.
