世界是独立于我的意志的。
The world is independent of my will.
The best things in life are the people we love, the places we've been, and the memories we've made along the way.
Even if we're apart, our hearts are always together.
The beauty of instrumental variables is that they allow us to see the world in a new light.
"History is a nightmare from which I am trying to awake."
宁可一人受苦，不使民族悲伤。
