Summary
Friendship depth is a product of time and vulnerability with quality based on the availability of support. People with 8/10 trust in others are happiest, in the best health, and have the highest incomes. The Price equation proves that altruistic behavior is good for the population but not necessarily individual. Narcissism (letting status define self worth) is a modern epidemic of the same magnitude as obesity. Understand your personal biases when judging friends, including egocentric anchoring where we assume others think and act too similar to ourselves. White lies are beneficial so we evolved to not perfectly read emotions. Love is an irrational commitment to an individual and will cost you 2 close friends.
“The only thing that really matters in life is your relationships to other people”
“Overall, friendship variables account for about 58% of your happiness”
“If you want to go fast, go alone. If you want to go far, go together”
