If I can do enough of the right things, I will have established my value. Identity is the sum of my achievements. Hence, if I can satisfy the boss, meet the needs of my spouse and children, and still pursue my dreams, then I will be somebody. In Christian theology, such a position is called justification by works. It assumes that my worth is measured by my performance. Conversely, it conceals a dark and ghastly fear: If I do not perform, I will be judged unworthy. To myself I will cease to exist.
