Do not speak of hardships, do not boast of joys, do not meddle in trivial matters. There is no true empathy in the world, not all fish live in the same pit. Your grievances are your own, your happiness is yours, there's no need to bring them out; it is meaningless. Ten things can't be better than three, and three can't be better than one excellent thing. First learn to eat, then learn to enjoy old age. It is better to chase the wind than to wait for it to come; there is no continuous, no apparent bend, no withering, no apparent joy, no flat ground, no apparent high mountain. A round moon in the sky, ten thousand miles of brightness on earth. Read more books to cultivate a lofty and righteous spirit.
