You have probably met this advice in a recent book: life is not short, most of it is wasted, and spent with care it is long enough. The idea is about 2,000 years old. The earliest source we can find is Seneca’s On the Shortness of Life, written c. 49 CE. It kept coming back, in Montaigne’s Essays in 1580, Johnson’s Rambler in 1751 and Lubbock’s The Pleasures of Life in 1887, none of them crediting anyone for it that we can find, and Burkeman’s Four Thousand Weeks in 2021 names Seneca. One saying on this page argues against it: the physicians’ “life is short”, about 450 years earlier, which Seneca quotes in order to reject it.
There is one older hint: Cicero’s On Old Age, in 44 BCE, says “a short term of life is long enough for living well and honourably”, but not that life is wasted or only feels short. That is half the idea, so Seneca’s De Brevitate Vitae 1.3 is still the earliest source we can find for the whole of it.
Seneca’s text reports the aphorism as “that well-known saying of physicians, that art is long but life is short”, the complaint he sets out to reject. It holds that life is short.

Johnson says “we want not time, but diligence, for great performances”, and that we squander much of our allowance while thinking it insufficient. The passage credits no one.

In his own words on Daily Stoic, Burkeman calls Seneca’s On the Shortness of Life “one of the most penetrating examinations of the matter” and credits Seneca: “Life’s not really short, he insists”.
