The quote from Barbara W. Tuchman's "The March of Folly: From Troy to Vietnam" highlights the importance of selflessness and practical insight in making wise choices. It implies that true wisdom is not driven by a desire for personal gain but rather by a thoughtful understanding of situations. This perspective can lead to decisions that benefit the greater good rather than serving individual ambitions.

Tuchman's assertion encourages us to reflect on the qualities that contribute to effective leadership and decision-making. By prioritizing common sense over personal motives, individuals can navigate complex scenarios more judiciously, fostering outcomes that are more equitable and beneficial for society as a whole.
