Why am I a person who can't joke?

You are too serious, and the rest is reasonable.

Actually, you don't have to take it seriously There are many things in this world that need not be taken too seriously. Think about it. Your life is very good, the sky will not fall, and all your relatives and friends are still alive, which is good for you. What do you care? Sometimes being too serious is tantamount to asking for your own punishment. The happiest people in this world are those who can play tricks, like joking and take nothing seriously.

Let me tell you a trick. You can take everything others say to you as a joke. Even if someone tells you seriously, you should treat it as a joke. Although this is extreme, it can cultivate your joking characteristics. Usually, we should pay more attention to reading joke books, humorous comedies and comic sketches. In short, don't make yourself reasonable, so others will think you are boring.
