Be the story you tell yourself. Timothy Wilson Said:

…the “do good, be good” method. It capitalizes on the tried-and-true psychological principle that our attitudes and beliefs often follow from our behaviors, rather than precede them. As Kurt Vonnegut famously wrote, “We are what we pretend to be, so we must be careful about what we pretend to be.“ People who do volunteer work, for example, often change their narratives of who they are, coming to view themselves as caring, helpful people. Well-designed studies have shown that teen girls who participate in community service programs do better in school and are less likely to become pregnant.
