Some of the happiest people I know have the least amount of worldly possessions

That has been my experience as well... and this doesn't imply their are either rich or poor, but more that they have a clear mind of what they want out of life. I know a few people that have been backpacking for years, enjoying their story.

I look at it and say... "You know what? - this person is deprogrammed... I love it.. " - I almost envy those who live a simpler life and hope to one day emulate them.
