Adopted from the following great insight shared by Dan Ariely in his book Predictably Irrational shows that psychologically all human beings are prone to lie to ourselves in order to feel better..
We all want explanations for why we behave as we do and for the ways the world around us functions. Even when our feeble explanations have little to do with reality. We’re storytelling creatures by nature, and we tell ourselves story after story until we come up with an explanation that we like and that sounds reasonable enough to believe. And when the story portrays us in a more glowing and positive light, so much the better.
