John Dos Passos, in his book "Three Soldiers," emphasizes the importance of actively experiencing life rather than merely observing it passively. He compares life to a box of bonbons, suggesting that it should not be kept untouched and unused. Instead, it should be savored and fully enjoyed. This metaphor highlights the notion that life offers opportunities and experiences that should be embraced rather than ignored.

Through this perspective, Dos Passos encourages individuals to engage with their surroundings and make the most out of their lives. The essence of his message is that life is fleeting and should be actively utilized, reminding readers that the true richness of life comes from participation and engagement rather than mere possession.
