habit: a powerful neural pathway that provokes mostly unconscious activity, which is helpful when it allows you to perform routine functions without much mental energy (such as walking, driving a car or lifting a cup to our mouth), but unhelpful when it confines your life into narrow ruts, depriving you of novelty and spontaneity.
happiness traps: common discretionary activities that may consume many hours of your life, but beyond relatively brief periods, provide relatively happiness and may actually depress you. Such lifestyle traps include consuming goods and media, overwork, shallow relating, overwork and substance abuse.
macro-joyshift: a complex joyshift that usually involves day, weeks or even months of preparation before it delivers a major primal happiness nutrient, such as a new relationship, a fulfilling job or extended travel.
the paleo emotional diet: analogous to the "paleo diet" except the nutrition is experiential not food, and the wellbeing is emotional not physical. Both diets derive from the idea that our bodies are optimized for the hunter gatherer world where the human genome evolved.
primal happiness principle: thanks to evolution and our genes, the activities that produce the greatest happiness today are modern versions of the behaviors that were essential to human survival during the eons when our ancestors lived as nomadic hunter gatherers on the African plains.
primal nutrients: the relatively few experiences that were essential for survival as nomadic hunter gatherers in the African grasslands, and which the human genome evolved a deep attraction to, and when experienced today produce great joy.
