In Malcolm Gladwell's "David and Goliath," he emphasizes that knowledge gained through challenges and necessities often has a greater impact than knowledge acquired with ease. This concept suggests that when individuals face difficulties, they tend to engage more deeply and develop a stronger understanding of the lessons at hand.

Struggles can foster resilience and adaptability, equipping individuals with skills and insights that easy learning may not provide. Gladwell argues that overcoming obstacles not only enhances personal growth but also allows individuals to navigate future difficulties more effectively, often leading to greater success and fulfillment.
