Use these scientifically rubber-stamped pointers to make better, brighter decisions: (a) Avoid negative things that you cannot grow accustomed to, such as commuting, noise, or chronic stress. (b) Expect only short-term happiness from material things, such as cars, houses, lottery winnings, bonuses, and prizes. (c) Aim for as much free time and autonomy as possible since long-lasting positive effects generally come from what you actively do.
