Book summary: Pragma

Danger flags

- before a person does something bad, there's often predictable signs that they were going to do it

Choose your companions wisely
- someone who is usually experienced periodically screws up a task
- do not employ people for areas where they are already flagged

but very expensive to constantly maintain this cognitive overhead

- avoid hiring people who get very self-destructive when anxious
- test them with small mission

- Machiavelli: The Prince

its much safer to be respected than loved

preferable to be both if possible
- people promise you the sky (love you) when you are in power and treating them nicely and doing them favors - promises which won't be fulfilled when crisis hits or war breaks out
- if someone truly respects you, some sort of liking and shared understanding tends also to emerge

- It is better to cultivate one very sharp skill than be mediocre at everything with no danger flags
- Grim determination is a good trait to cultivate - follow through to the bitter end
- *Ray Dalio: Principles* - how to live up to your potential
