First, if you are not good enough, your contacts are worthless. Not pursued, but attracted. Only equivalent exchange can get reasonable help-although it sounds cold, it is true.

Second, people's two eyes are parallel, but people are not equal. People's ears are on both sides, but they always listen to one side of the story. People only have one mouth, but they can always say two words.

Third, people who really love you may not say a lot of things that love you, but they will do a lot of things that love you. Those who don't care about you, on the surface, make a fuss, and swear to make people warm, and what they do behind your back makes people feel chilling.
