Economic notions of prosperity often compete or interact negatively with health, happiness, or spiritual notions of prosperity. For example, longer hours of work might result in an increase in certain measures of economic prosperity, but at the expense of driving people away from their preferences for shorter work hours.
In Buddhism, prosperity is viewed with an emphasis on collectivism and spirituality. This perspective can be at odds with capitalistic notions of prosperity, due to their association with greed. Data from social surveys show that an increase in income does not result in a lasting increase in happiness; one proposed explanation
to this is due to hedonic adaptation and social comparison, and a failure to anticipate these factors, resulting in people not allocating enough energy to non-financial goals such as family life and health." http://en.wikipedia.org/wiki/Prosperity
A successful life is not always a high-achieving life. Sometimes it is about accomplishing a worthwhile goal, even a private, personal victory. Sometimes it is about improving one's character. Sometimes success is best defined by living into one's own personal mission, or finding a meaningful purpose to organize one's life around. And sometimes it is about learning how to live in peace, happiness, generosity and love.
