Surprisingly, selfishness isn\u2019t always a product of narcissism or pure ego. Often it\u2019s the product of insecurity. The me-monster inside of you won\u2019t die because you\u2019re so worried you don\u2019t measure up, that you\u2019re not enough, and as a result, you really don\u2019t like yourself. Which is why you can\u2019t stop thinking about yourself. And it\u2019s damaging your relationships, your parenting and even your performance at work.
