This chapter takes the idea of humility and applies it to the way that large, powerful countries ought to behave.
If large countries are humble, then they'll retain their influence.
If large countries spend all their time bossing around all the other countries, they'll eventually fall and will be taken over by the smaller countries they used to pick on.
You can take this advice and apply it to your own life as well.
When you're the boss, don't be a jerk to your employees.
When you're rising up through the ranks, don't be ruthless.
You never know when you might lose your power and need a helping hand.
