1. SINGAPORE
"There's a lot of pressure to perform to expectations and conform to norms here so I think that overrides our personal happiness ... Most of my kids are very focused and spend long hours dedicated to school. As a teacher you want what is best for your students but you can't help but feel they miss out on a childhood." -- Fung Yeewai, 25, part-time teacher.
2. ARMENIA
"As for me, I feel fine and see no reason to be unhappy. But many people I know feel unhappy about various problems." -- Lilit Babadzhanian, 28, medical worker, Yerevan.
4. GEORGIA

4. SERBIA
"What is there to be happy about? Poverty, no jobs and even the possibility of more wars? No way. The only strategy for many young people here is to get out as soon as possible. The sooner, the better." -- Petar Jovanovic, medical student, Belgrade.
7. BELARUS
"I want to go abroad. It's stupid to live in a dictatorship in the middle of Europe. It's fear that makes Belarusians unhappy. Everyone is afraid of being crushed by the state. Living in Belarus means no freedom, no money and no future." -- Maxim Luksha, 20, university student.
8. LITHUANIA
"Lithuanians feel unhappy, because they believe that there is no sociological justice in the country. The conditions for family business are not conducive, and the basis of Lithuanian economy is big business. The wages of employees are low, and the whole social situation is unfair. This makes the main difference between Lithuania and other countries in Europe." -- Vladas Gaidys, director of public opinion firm Vilmorus, Vilnius.
