Sam Stewart

“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 - though all the while that very day which you are devoting to somebody or something may be your last. You act like mortals in all that you fear, and like immortals in all that you desire.”
― Seneca, On the Shortness of Life: De Brevitate Vitae (A New Translation)
