I feel people who work on to fill the void of their inner core, will always tend to stay happy. Here subjects who carried a void of low self esteem, by changing their looks coupled with how they viewed themselves and the world later on, had a powerful effect. The same could be achieved if you had a good bank balance, and spent it on the matters, which yields good experiences, and in turn changes the way you view yourself and the world. Most of the time, it requires you to stay humble. But usually people don't prefer this. :)
