Happiness is something we all aspire to, yet its key factors are still unclear.

Some would argue that wealth is the most important condition as it determines one’s living conditions. Nevertheless, some would rightly point out that rich people aren’t systematically happy. On the contrary, one’s social relationships (family, friends, etc.) contribute just as much to his happiness. Finally, some would argue that the policies implemented by governments are what really determine one’s happiness, as they determine indirectly our living conditions and social interactions.
