The influence of my family environment has given me a negative personality. Whenever something goes wrong in my life, I will be unhappy. If a person has no long-term worries, he must have short-term worries. It is me who is talking about it. I'm either worrying about the past or worrying about the future. I also discovered that everyone is more or less unhappy, so I wrote this book to record how humans can be happy. Summarize ways and means.
Purpose: Summarizing methods for human happiness and resisting depression
