Kind and helpful people do things that are praised but not appreciated. It's called selflessness. In a literal sense, comfortable people "reject themselves." And this can lead to fatal consequences in the form of low self-esteem and loss of self. Therefore, it is important to defend your boundaries in time and foster healthy selfishness. Perhaps some people will turn their backs on you. Whoever has used you before will stay away. Anyone who complained about your life, not wanting to listen, will lose interest in you. And whoever used your friendly services, giving nothing in return, will turn away from you if you stop serving him. But is it a loss?
