Seneca wrote 124 letters to his friend Lucilius in the last years of his life. These are the lines worth carrying with you from every one of them, each linked to the full letter so you can read the whole argument behind it.
Every quote on this page comes from our new modern translation.
Sixteen to Start With
Nothing, Lucilius, is truly ours — except time.
It isn’t the person who has too little who is poor, but the person who craves more.
I will tell you a love-potion mixed without drugs, herbs, or any witch’s spell: if you would be loved, love.
There are more things likely to frighten us than to crush us; we suffer more often in imagination than in reality.
If you live according to nature, you will never be poor; if you live according to opinion, you will never be rich.
What is wisdom? Always wanting the same things, and always refusing the same things.
You need a change of soul rather than a change of climate. Though you may cross vast stretches of sea, your faults will follow you wherever you go.
We break life into little pieces and fritter it away.
Fortune has no jurisdiction over character.
The wage of a good deed is having done it.
We should not strive to live long, but to live rightly.
To have something can be taken from us. To have had it, never.
When a man doesn’t know what harbor he’s making for, no wind is the right wind.
As long as you live, keep learning how to live.
Enough is never too little, and not-enough is never too much.
Nothing is heavy if you accept it with a light heart.

No evil is great if it is the last evil of all.
5 On The Philosopher’s Mean
Just as the same chain links the prisoner and the soldier guarding him, hope and fear keep step. Fear walks behind hope.

6 On Sharing Knowledge
No good thing is pleasant to possess without friends to share it.
If wisdom were handed to me on the express condition that I keep it locked away and never speak it, I would turn it down.

13 On Groundless Fears
There are more things likely to frighten us than to crush us; we suffer more often in imagination than in reality.

December used to be a month; now it’s the whole year.

A person who has to supply a reference for everything he says shows that he has no standing of his own.
