So why not be nice to others and leave three points for yourself? There are many reasons. First of all, there should be a little distance between people, because everyone is an independent individual. If there is no distance and no ego at all, it will be unbearable for both the giver and the receiver for a long time. If you give everything to yourself, it will be unbearable for a long time, and so will the people who are helped, because it will hurt self-esteem, break your peace, and sometimes cause bad relations. This principle also applies to parent-child relationship. If parents care too much about their children for a long time, the children will feel great pressure and pain, which will affect the parent-child relationship. In fact, it is not uncommon for two people to have a particularly good relationship, or for parents to be particularly good to their children. It is often reported that children will hate their parents' doting when they grow up, and even hate their parents' excessive intervention. Secondly, if you are too kind to others and have no reservations, it will sometimes be dangerous, because not everyone is as good as you. Others may take advantage of your kindness and deprive you of everything, and then they will regret it. And some people may be protected if they are hidden bad guys and are prepared too well. Therefore, you must be careful when dealing with people. You can't give up my heart completely. Pay attention to protect yourself and respect others.
People should be measured in their communication, be good to others and be good to themselves. Everyone needs to have their own self and space. Don't be too kind to others. This is both protecting yourself and respecting others.
