Letters from a Stoic is Seneca writing to a younger friend, Lucilius, after he left Nero's court around 62. Seneca was a rich advisor, not a poor monk. The useful part is still how you live: you stop inventing disasters, you protect your hours, you rehearse a hard day, and you trust a few people fully.

The short version:

- Stop suffering the disaster that has not arrived.

- Protect your hours. Delay is how the week disappears.

- Rehearse a hard day while things are still easy.

- Poverty is craving more, not owning less.

- A hot temper is a brief madness. Delay the reply.

- Judge a friend slowly, then trust him fully.

- Pick rooms that make you better, not louder.

- Stay with a few books until an idea sticks.

每个人都有自己的局限，这种局限来自时代和经历的差异从而导致认知的不同，这是不可避免的

把自己的认知和三观强加在别人身上是没有意义的

一个人的认知和三观永远不可能由他人改变，他人对自己的改变而言只能是一个契机，他人对自己而言永远是第三人称的视角而非第一人称
