快乐有益于身体，但悲伤才能发展心灵的力量。

On vacation go to the most remote place on your itinerary first， bypassing the cities. You‘ll maximize the shock of otherness in the remote， and then later you’ll welcome the familiar comforts of a city on the way back.

Stories you read when you're the right age never quite leave you. You may forget who wrote them or what the story was called. Sometimes you'll forget precisely what happened, but if a story touches you it will stay with you, haunting the places in your mind that you rarely ever visit.

A culture of accountability drives performance.
