It is not that we have a short time to live, but that we waste a lot of it.Seneca
Life is long if you know how to use it.Seneca
You act like mortals in all that you fear, and like immortals in all that you desireSeneca
We are not given a short life but we make it short, and we are not ill-supplied but wasteful of it.Seneca
Can you ask a greater stupidity than to wonder that those whom they have striven to please are the first to be ungrateful?Seneca
Indeed, no one is allowed to live in the past or in the future, for those who live in the past have already lost their life, while those who live in the future have not yet begun to live.Seneca
But the greatest loss of time is delay and expectation, which depends upon the future. We let go the present, which we have in our power, and look forward to that which depends upon chance, and so relinquish a certainty for an uncertainty.Seneca
People are frugal in guarding their personal property; but as soon as it comes to squandering time they are most wasteful of the one thing in which it is right to be stingy.Seneca
You are living as if destined to live for ever; your own frailty never occurs to you; you don’t notice how much time has already passed, but squander it as though you had a full and overflowing supply.Seneca
Believe me, it is the sign of a great man, and one who is above human error, not to allow his time to be frittered away: he has the longest possible life simply because whatever time was available he devoted entirely to himself.Seneca
