Jim’s narrative of his heroic acts is valuable because he records them modestly, giving us an insider view of heroism that is not very glamorous. Jim is not arrogant, but instead is humbled by his mistakes and successes. He takes full responsibility for his errors rather than finding excuses for them, and he confesses to moments of panic, indecision, and regret rather than bragging exclusively of his successes.
