In behavior, normal means not deviating very much from the average. "Not normal" is often used in a negative sense (improper, sick, etc.). Abnormality varies greatly in how pleasant or unpleasant this is for other people; somebody may half-jokingly be called "pleasantly disturbed". Examples of "normality" are mainstream, temperance, vanilla sex, equilibrium, stability, reality, peace, health, middle way; contrast these with eccentricity, perversion, paraphilia, intersexual, disease, disability, mental illness, addiction, war, crime, fantasy, dream, hallucination, illusion.
Some terms could fit in both lists, for example boredom: too much "normality" can be boring, but boredom is a kind of suffering, which can be considered "not normal".

- Quote: Keep it Real! (Stop being fixated by dreams of unachievable things, focus on the reality of the present situation.)
