Seneca identifies time as our most precious and truly personal possession. While external things can be taken from us - wealth, status, health, even relationships - time belongs to us completely while we have it. Yet we often treat time carelessly, wasting it on trivial pursuits while being protective of lesser possessions. The irony is that we guard our money carefully but spend our time freely, when time is far more valuable and irreplaceable. This perspective calls us to be more intentional about how we use our hours and days, recognizing that time is not just something we have but something we are. How we spend our time is how we spend our lives.
