The key ideas in Letters from a Stoic

Time is all you own

Seneca tells Lucilius to take back his time. Some is snatched from us, some slips away, and most we simply waste, yet it's the one thing that's truly ours. We're dying a little every day, he adds, because the years behind us already belong to death.

Choose friends slowly

Lucilius calls a man his friend, then warns Seneca not to discuss his affairs with him. Seneca pounces. Take a long time deciding whether someone is a friend, he says. Once you have decided, trust them completely and speak to them as freely as you would to yourself.

Rehearse being poor

While Rome parties through the Saturnalia festival, Seneca, a very wealthy man, suggests setting aside a few days to live on the cheapest food and roughest clothes. Then ask yourself whether this is what you were so afraid of. It's a rehearsal, so the real thing can't frighten you.

Lines worth underlining

  1. Time

    Guard your time. People who'd never hand over their money give away their hours without a thought.

  2. Reading

    Read a few good writers closely rather than skimming lots of them.

  3. Friends

    Think hard before you make someone a friend. Once you do, trust them fully.

  4. Crowds

    Crowds tend to make us worse. Spend your time with people who'll make you better.

  5. Fear

    Most of what we dread never happens, and the rest usually hurts less than we pictured.

A story from the book

The old man at the door

At his country house, Seneca complains the building is crumbling. His bailiff says it isn't neglect. It's just old, and Seneca built it. Then a toothless old man at the door turns out to be Felicio, a boy Seneca once brought toys for. Seneca decides to enjoy old age.

Hot take · true or myth?

A Stoic can own fine things, as long as he isn't attached to them.

See the book's answer

True. Seneca admires the person who uses earthenware as if it were silver, and just as much the one who uses silver as if it were earthenware.

One thing to try

Keep a time ledger for a day

Seneca admits he can't claim to waste no time, but he can say what he wasted and why. Try that for one day. Note what each hour went on, and circle the ones someone else took without you really agreeing. Tomorrow, take one of those hours back.
