What about introverted people? The majority of people are extroverted, so this studies result make sense, but a significant number of people are introverted. A simplified definition of introversion is a person whose energy is drained after spending time with people. So the recipe for happiness for an introverted person doesn't necessarily follow the same pattern.

After all, the number one piece of advice was "spend time with the right people". But maybe it applies for introverted people too. For me, top of the list for right people is my wife. We can be "alone together". Perhaps curled up together on the couch reading.

And introverted doesn't mean that we don't enjoy the company of good friends -- it just means that we need some alone time after to regain our energy. Good friends are often significantly energy draining but are significantly happiness increasing.
