1. You must trust others before you can gain their trust! Get to know a person first, and then try to trust him. It is dangerous to trust without understanding, and it is indifferent to trust without understanding him. Trust is relative. Don't trust him when he cheats you (that is, when someone reminds you without your knowledge). Unless something important happens, a person's personality and temper will not change much. I have a limit to the number of times others lie to me: no more than three times, no more than three times! 2. When honest people say honest words, do honest things! 3. Communicate more to enhance understanding! Trust is based on understanding. Trust without understanding is blind trust. Trust can be cultivated. As long as this person is worth cultivating, you must trust others first if you want others to trust you! Imagine, will you cheat people who trust you again and again? If you really do this, then you are not a trustworthy person and it is not worth cultivating trust. 4. Promise must be fulfilled! 5. Evaluate yourself and others correctly in interpersonal communication. As the old saying goes, "You only know when you are expensive". What is "expensive", why "expensive" and "expensive" explain its difficulty. It is really not easy to know yourself correctly. In the wrong self-evaluation, the biggest obstacle to communication is inferiority and pride.
