An important term to add to your vocabulary: "Woohoo – The indefinable property that lets our brains represent some experiences as powerful, important, or pleasurable. Woohoo is the subtle difference between ordinary and exciting, the factor that makes just another stranger into your friend, your teacher, or your lover. Woohoo is what turns an activity into a passion; it’s what changes noise into song, foot movement into dance, travel into adventure, procreation into eros, and biological processes into a life worth living. Woohoo is the measure of intensity. It’s what continues to draw your attention, moment after moment." -- Phil Farber
