If you are honest, there will be more people deceiving you; if you are useful, there will be more people looking for you; if you are useless, there will be more people far away from you, which is the reality. Don't try the heart, it will disappoint you. If you know something, you don't have to say much. Some people just know each other and don't need to know each other deeply. Do what you should do well, who knows the good or the bad in your heart, the sharp three points, the silly three points, leaving four points for time! There are two things in the world that should not be looked at directly. One is the sun, the other is the heart. The former hurts the eyes, the latter is sad!
