1. All-or-Nothing Thinking. This refers to your tendency to evaluate your personal qualities in extreme, black-or-white categories. For example, a prominent politician told me, “Because I lost the race for governor, I’m a zero.” A straight-A student who received a B on an exam concluded, “Now I’m a total failure.” All-or-nothing thinking forms the basis for perfectionism. It causes you to fear any mistake or imperfection because you will then see yourself as a complete loser, and you will feel inadequate and worthless.
