Seneca emphasizes the importance of preparing for difficult times during periods of prosperity. He suggests that by subjecting oneself to lesser comforts—like frugal meals and minimal clothing—one can confront fears and build mental resilience. Through such experiences, individuals can evaluate their true limits and recognize that what they previously deemed terrible may not be as daunting as imagined.

Additionally, Seneca draws parallels between preparation and military training, noting that soldiers work hard during peacetime to ready themselves for future battles. He advocates for a proactive mindset, urging people to develop inner strength and fortitude when life is favorable, so they are ready to face any adversities that may arise.
