Being kind can go a long way. It is a common belief in psychology that people use certain mechanisms when adapting in life. One of the mature, healthy ways to adapting in life is called altruism. Altruism is essentially the process of being unselfish and helping others. Selfishly, helping others helps ones own self as well. In addition, being kind can open the right doors for people. Who does not want to work or be associated with a kind person? Conversely, if one is rude or unkind, those doors are shut and this can result in destructive ways to deal with life, such as being reactive, angry, blaming others, etc.
