Meaning

Seneca is asking the reader to resist treating life as a single stretched-out span with endless time still ahead. By approaching each day as a complete life unto itself, a person brings the full weight of attention and care to the present moment. The beginning of that day matters the same way a beginning matters, and the close of it deserves the same reflection that the close of a life deserves. It is a reframing designed to defeat postponement and half-attention.

Context

The Letters to Lucilius is a long series of letters Seneca wrote to a younger friend, exploring Stoic philosophy in practical and personal terms. The letters cover topics ranging from friendship and solitude to ambition and the proper attitude toward death. Questions about how to use time well appear throughout the collection, and this line belongs to that recurring concern. Seneca was writing in an era when Stoic thought placed great emphasis on living in accordance with reason and treating the present moment as the primary arena of a well-lived life.
