It's important and most times imperative that I give of my time, information and resources to the countries I visit, including my own- USA. I cannot just go and take (the natural beauty, the happy smiles, the warm feelings) from the countries I visit and not give back somehow in some way.
There's a reason why people with money travel to other countries for relaxation, fun and happiness. The inhabitants must know something we don't about the real "keys" to life.
If you take the time to listen- they may share it with you too.
