I've been to a lot of places, and I still value things like the books that I've read, personal relationships, real experience etc etc a lot more.
Sometimes all travel contributes to is pretentiousness.
yes, just the fact of knowing a foreign language, (well), tells a lot about a person.
So, I think living in different parts of the world is only indirectly useful. The important thing is to live in a new environment among people with a different culture.
I don't even think spending time overseas in the industrialized west is much of an eye-opener. Appalachia would probably be just as much of an experience for a lot of people.
The horrible problem here is that unless one has lived abroad for a while in a country with a different language and culture than one's own, there's no way a person can see value in it. But if you don't have that experience, you will always drag behind those who do.
The traveled ones are always much more rational in thought, and open in mind, and aware of the possibilities. Non traveled folk tend to be more rigid, narrow in though and unable to grasp concepts that may be foriegn to their history.
As to the rest, my biggest beef is that he assumes all people are born entrepreneurs - even if he says otherwise. One must remember that although college can be a bore for a bright individual, it can be a saving grace for a person that is, well average.
