"It Is Not That We Have a Short Time to Live, but That We Waste Much of It"
In On the Shortness of Life Seneca refuted the common complaint that "life is short," holding that with rational planning and focus on what truly matters, life is in fact ample enough, the problem being that people squander vast time on anxiety, luxury, and meaningless affairs — "it is not that we have a short time to live, but that we waste much of it" — an insight still repeatedly quoted as a philosophical maxim in the field of time management.
Composure in a Forced Suicide
When Seneca was ordered by Nero to take his own life, according to the historian Tacitus he behaved with extraordinary calm, first opening the veins of his wrists, and, the blood flowing slowly with age, also taking poison and a steam bath, all the while conversing composedly with the friends and secretaries present about the philosophy of the soul and death — this detailed account of his death was thereafter long seen as a classic example of the Stoic ideal that "a philosopher should face death with reason and dignity" put into personal practice.
