Seneca wrote On the Shortness of Life to Paulinus, who was in charge of Rome's grain supply, urging him to shift his focus from managing grain to managing his life. Seneca begins by challenging the common complaint that life is too short, asserting that people waste their time on fleeting pleasures and worrying about their reputations. He contends that the quality of time spent is more important than the quantity. Seneca uses historical figures like Augustus, Cicero, and Livius Drusus to illustrate how even the powerful can waste their time.
