Notes8
Chapter 4 — Key insight
The Stoic distinction between things "up to us" and things "not up to us" is the central pillar of the entire philosophy.
On resilience
Adversity as a training ground, not a punishment. Each obstacle is an opportunity to practice virtue.
Quotes12
Do not seek for things to happen the way you want them to; but wish that what happens, happens as it is, and you will have a tranquil flow of life.
