An altruistic person may, for example, be more concerned with the happiness of others rather than their own. He or she may focus on improving the material and spiritual quality of the lives of those around them as opposed to taking a more self-centred approach. Bear in mind that psychological altruism means being motivated by others rather than self-interest. Biological altruism, on the other hand, is focused on performing acts that are in the good of the human race as a whole.
