This chapter explores the notion that excessive effort in investing may not always yield better results, using examples and evidence to support the idea. It also highlights the concept of being 'Harvard stupid,' where well-educated individuals make complex mistakes due to their intelligence and ego. Additionally, it shares a story about a young doctor who faces conflicting diagnoses from his professor but later realizes his initial diagnosis was correct.
