Gao Zi said: My life is an opportunity for misfortune and happiness. People can be satisfied with what they meet and abide by what they have born. I don't worry about gains and losses, and I don't lose my appearance because of honor and disgrace. Lotte knows that life is naturally ups and downs. Isn't it an opportunity for happiness? For example, some people pitch in fashion, run on the road, fly their dreams in Yanhan, and gallop, so they don't want to eat food, don't want to sleep in bed, don't know how to keep in good health, have taboos about daily use, and fascinate themselves with poison, just like stepping on the blade with a pillow, and the chance of disaster will take advantage of it. Can they quit without knowing it? So I said: "People who know that they are comfortable and self-sufficient are the foundation of happiness;" See the living room safe, with a comfortable nest; The way to get happiness is to ensure that you are well nourished in the morning and evening; Happy are those who play comfortably in the leisure mountain; Those who know three talents and avoid them will get a peace ring; Those who make strict friends get comfortable help. What's more, it's hard to live to 80 or 90 years old, and you can achieve longevity through internal cultivation. "So I recorded an ancient ready-made statement, and attached my own meaning as a book, entitled" The Happiness of Living ".
