1. You have to understand that no matter how hot the water is, it will still get cold, no matter how full the enthusiasm is, it will still fade away, and no matter how full the passion is, the person you love will still leave, so you have to be good and learn to grow up.

2. When you grow up, not many people seem to care about whether you are happy or not. Many people only care about whether you are successful or not. However, you must care about whether you are happy or not.

3. Not every "I'm sorry" can be exchanged for a "It's okay". Don't think that every apology can bring everything back to the same as yesterday. Sometimes an apology is just your relief, not the relief of others.

4. You can treat the world gently, or you can tolerate others' unscrupulous treatment of you. But you must let them understand that all your concessions are not because you are weak.

5. You can be a kind person, but you don’t have to be kind to unnecessary people. Remember this sentence: Everyone understands that people’s hearts change their hearts.
