The paper explores the dimensions of happiness capital among youth as joy-seekers in different contexts. Due to the increasing use of social networks, the youth are increasingly pursuing perpetual happiness. Happiness capital by itself motivates the youth to move better towards the goals of happiness. The present research examined happiness capital and development of youth of the age groups of 15-29 years through different variables. The research was conducted in Tehran City, in which 489 respondents were randomly selected from different parts and neighbourhoods of the city. It explored the forces responsible for not-ever-lasting happiness among the youth. It was mainly based on the hypothesis that "social and economic conditions such as income, employment, general quality of life and successful marriage create happiness capital within the youth". The research method used in this work was a combination of theoretical frameworks and empirical realities. The paper concludes that in the present changing and globalizing world, societies must make the necessary policies for the happiness and leisure pursuits of the youth in order to prevent the likely controversies.
