Abstract: One of humanity’s ultimate goals is the pursuit of happiness. With the development of behavioral decision making, researchers in this field began the exploration of happiness in recent years. Happiness rules in behavioral decision making may involve hedonic editing, less is better, peak and end rule, myopia and loss aversion. Based on these happiness rules, happiness increasing strategies were proposed as follows: how to communicate news to others, how to give gifts, how to use loss aversion to promote happiness, how to apply the peak and end rule to promote happiness, and how to overcome myopia.

Key words: happiness, behavioral decision making, happiness increasing strategy
