One of the mistakes we often make is that we often ask others to treat us as well as ourselves: when you smile at others, you want others to smile at you; If you help others, you hope they will always be grateful. In this way, I will live in the care of myself, and always think about whether it is worthwhile to do anything. We always put our lives in various coordinates, such as status in the ordinate and wealth in the abscissa, and then compare with others in this coordinate all our lives.
