最困难的是在当下富足地生活，而不让它被过去或未来玷污。
The hardest thing is to live richly in the present without letting it be tainted by the past or future.
Optimists tend to interpret their troubles as transient, controllable, and specific to one situation. Pessimists, on the other hand, believe that their troubles last forever, undermine everything they do, and are uncontrollable.
理解不平等需要超越平均水平。
译文：人生就像一场梦，百年光阴很容易就过去了。梅花绽放时，泉水开始涌动，雪花飞舞处，大雁不见踪迹，只留下一片空旷。不如一醉解千愁，等待春风到来。
