For US citizens, Peace Corps is one way to meet both of those goals. For people from other countries, there are similar organizations in many countries, and some that accept volunteers from almost anywhere (such as VSO and UN Volunteers).

Volunteers spend a long time in their host country, and really get to see things in depth (not just the tourist view).

Volunteers also get a chance to "change the world". Usually not in a particularly grand way, but a little education and inspiration can have a lot of ripple effects.

Of course, being based overseas, and having a fair amount of vacation time, volunteers also have opportunities to visit other interesting places and countries near their host sites.

Getting a reasonable living allowance and government-sponsored benefits sweetens the deal, but of course it doesn't offer nearly as much freedom as simply quitting your job and hopping on a plane.

That is not traveling in my book, though - it is staying abroad. I have no problems with working in another country.

I certainly agree that it is worthwhile to experience another culture at least once. I am not so sure about more than once, though.

IMHO "staying abroad" is the best form of traveling. You're not going to be steeped into the cultures of others until you live amongst them. Staying at the Hyatt and visiting all the mandatory sights by tour bus is probably the worst and least rewarding traveling experience money can buy.

In college my internships took me all across Canada, staying in each place 4 months at a time. All of those experiences have been invaluable to me, and taught me far more than any sort of vacation I've ever taken.
