Ruut Veenhoven, who studied sociology, rerseach an average in 95 nations from 1995 up to and including 2005. How much people enjoy their life-as-a-whole was evaluate on scale 0 to 10. On the top of 95 nations is Denmark and at the bottom of the countries is Tanzania. I think that these results depend on country’s political and economical situation, because in strong country people can meet they wants and feel happily. In my opinion Lithuania is not strong country, there are not good political and economical systems and so Lithuania is only on 85 place in 95 nations.
Psychologist Professor Edward Diener from the University of Illinois, USA, designed the test, which is measuring your happiness. Professor explains that three the most important influences on happiness are social relationships, the life satisfaction of most people is work or school, or performance in an important role and personal satisfaction with the self, religious or spiritual life, learning and growth, and leisure.
To sum up, happiness depends on various things. I think that people must more joy of that they have and less envy for others.
