Seek happiness in the ordinary, seek happiness in suffering, seek happiness in twists and turns. Happiness is a kind of tolerance, a kind of self-restraint, a kind of temperament, a kind of demeanor. No matter how hard the road ahead is, no matter how helpless life is, as long as you stay happy in your heart, there is no need to be depressed. Make yourself maintain a pure heart, gain it indifferently, and lose it calmly.
