Cersei on Being a Just Ruler
“A good king knows when to save his strength and when to destroy his enemies.”
So many of Cersei’s best lines are advice. In fairness, you could do worse taking advice from the most powerful woman in Westeros. She did get to her position mainly by cunning and pure dedication. While some of her advice is terrible, this one is just cold, hard, fact that should be taken to the bank for any aspiring despot.
