Seneca

“Enjoy present pleasures in such a way as not to injure future ones.”

“Life is like a play: it's not the length, but the excellence of the acting that matters.”

“Were all the geniuses of history to focus on this single theme, they could never fully express their bafflement at the darkness of the human mind. No person would give up even an inch of their estate, and the slightest dispute with a neighbor can mean hell to pay; yet we easily let others encroach on our lives—worse, we often pave the way for those who will take it over. No person hands out their money to passersby, but to how many do each of us hand out our lives! We’re tight-fisted with property and money, yet think too little of wasting time, the one thing about which we should all be the toughest misers.”

“Friendship always benefits; love sometimes injures.”

“But those who forget the past, ignore the present, and fear for the future have a life that is very brief and filled with anxiety: when they come to face death, the wretches understand too late that for such a long time they have busied themselves in doing nothing.”

“Time adds nothing to the finer things in life.”

“Luck is what happens when preparation meets opportunity.”

“What man”

“The time will come when diligent research over long periods will bring to light things which now lie hidden. A single lifetime, even though entirely devoted to the sky, would not be enough for the investigation of so vast a subject... And so this knowledge will be unfolded only through long successive ages. There will come a time when our descendants will be amazed that we did not know things that are so plain to them... Many discoveries are reserved for ages still to come, when memory of us will have been effaced.”

“As is a tale, so is life: not how long it is, but how good it is, is what matters.”

“The time will come when diligent research over long periods will bring to light things which now lie hidden.

“In consequence, when the pleasures have been removed which busy people derive from their actual activities, the mind cannot endure the house, the solitude, the walls, and hates to observe its own isolation. From this arises that boredom and self-dissatisfaction, that turmoil of a restless mind and gloomy and grudging endurance of our leisure, especially when we are ashamed to admit the reasons for it and our sense of shame drives the agony inward, and our desires are trapped in narrow bounds without escape and stifle themselves. From this arise melancholy and mourning and a thousand vacillations of a wavering mind, buoyed up by the birth of hope and sickened by the death of it. From this arises the state of mind of those who loathe their own leisure and complain that they have nothing to do, and the bitterest envy at the promotion of others. For unproductive idleness nurtures malice, and because they themselves could not prosper they want everyone else to be ruined. Then from this dislike of others' success and despair of their own, their minds become enraged against fortune, complain about the times, retreat into obscurity, and brood over their own sufferings until they become sick and tired of themselves.”

“Every new beginning comes from some other beginning's end.”

“Begin at once to live, and count each separate day as a separate life.”

“It's not that we have little time, but more that we waste a good deal of it.”
