Confucius said it was unhealthy.

1, encounter difficult worries, eat badly, sleep badly, and think wildly, which is no different from physical and mental health; Why don't you read a book to find out? If you can't see clearly, look at the present history. The present difficulties have happened in history, and the book has its own answers.

2. Be filial to parents at home, respect teachers and respect morality outside, be cautious, keep your word, have the heart of fraternity and the virtue of benevolence and righteousness. Read more books after you have fulfilled the basic principles of being a man. But the knowledge in books is not the most important, and the truth of being a man is the greatest wisdom.

3. I am not afraid that others will not understand you, but I am afraid that you will not understand others. Dealing with people, knowing his personality, you can get along better. Don't flaunt yourself, observe others more.

People who study for knowledge are not as happy as those who are interested in learning, and those who are interested are not as happy as those who find happiness in learning.
