"Absolutes do not exist in this universe. If you try to force your experiences into absolute categories, you will be constantly depressed because your perceptions will not conform to reality. You will set yourself up for discrediting yourself endlessly because whatever you do will never measure up to your exaggerated expectations. The technical name for this type of perceptual error is "dichotomous thinking." You see everything as black or white--shades of gray do not exist."
