A quick definition of All-or-Nothing thinking: We tend to believe that things, including ourselves, are either right or wrong, good or bad. Typically, this kind of thinking comes from your child brain which learned that right and wrong, good or bad were the hallmarks of life and were the benchmarks by which you (and others) were judged. The truth is that there are few absolutes in the world, very few things we can know for certain, and very few things for which there is only one right answer or one right way of thinking or approaching something. Life is subjective, after all. No two people experience the the same situation in exactly the same way.
