Quality is not an act, it is a habit.
"The only real equality is in the cemetery."
The truth is a knife, and lies are the bandage.
——在遗嘱上签名后，对在病榻的同志们说，1925年3月11日
We must embrace change, or risk being left behind.
In the quest to understand quantum gravity, we are like children playing on the shore of a vast ocean, occasionally finding a smooth pebble or a pretty shell, while the great ocean of truth lies undiscovered before us.
