If you can't find the value of your existence, then think about how to give yourself an explanation, to your parents, to your friends and to your favorite people!
The meaning of living is to find the meaning of living;
1) Everyone has his own meaning to live. People want to live for themselves, the meaning is to work hard for their own goals, and success requires sweat. Success, failure, laughter and crying are all fully experienced and enjoyed. On the contrary, if a person has no ideal and what he does is for others to see, what can he experience? People can't even experience and enjoy these things by themselves when they are alive.
2) Look at the world with your heart. Not everyone in this world is going well, it's up to you to solve it yourself. For example, when you were walking, you were hit by someone and someone apologized to you. Sometimes you still feel angry, but you didn't expect the person who hit you to feel worse than you. Think about the sentence "Happy is also a day, unhappy is also a day, why not be happy every day?"
3) Life is easy, life is easy, but life is not easy. Don't worry, there are almost as many people in this society as you, but they all live happily. Not everyone can succeed. As long as you work hard at everything and take life seriously, as long as you take every day seriously, no matter what your life is like, I believe it will be wonderful. Bottom line: people should live a wonderful life, come on!
