4.10 Adaptation Theory of Well-being

(Diener, Lucas, and Scollon 2006) People tend to return to their previous level of happiness after traumatic events. we tend to stay in a long-term disposition.

(Lyubomirsky, Sheldon, and Schkade 2005) long-term happiness depends 50% on a person’s genetic set point, 10% on circumstances (whether you, how rich, how healthy they are), and 40% on what they choose to think and do. Hence, even if our friends are happy, they happiness will wear off, and return us the original level.
