Everything is about perspective. I am not happy with my current financial situation although I reside in a 4 bedroom house in NJ on a 1/4 acre of property near NYC in what most people would consider an affluent area.
In my visits to places like the Phillippines I have found that people seem to be happy on much less. People are lucky (in the Phils) to own a used Honda Civic where as if we go to the local community college parking lot you will see many young students with such vehicles.
However, its this unhappiness that drives people forward. Walk through a place like NYC, Chicago or Washington DC. Would these buildings have been erected if someone said to themselves..."Hey this is good enough".
The fact of the matter is that unhappiness with the current situation is what makes you change it. It drives you forward. Unhappiness is good, it promotes change...
