This one is for you economists out there.
[M]ost people do not do the simple things that would be conducive to their happiness, even when they know what they are. Most people fall into one or more of the following traps. They spend a lot of time with people they do not much like. They do jobs they are not enthusiastic about. They use up most of their “free time” (incidentally an anti-hedonistic concept) on activities they do not greatly enjoy. The reverse is also true. They do not spend most time with the people they like most; they do not pursue the career they would most like; and they do not use most of their free time on the activities they enjoy most. [Richard Koch – The 80/20 Principle]
