Growing up in SoCal, spent a lot of my teen years in Mexico - that was fun.
Graduated from college in '73 on a Tuesday and was on a plane Friday bound for Amsterdam.
Lived there (in Delft), for two years.
Lived 6 months in Al Khobar, Saudi Arabia in '80, (actually saw a beheading in Dammam), and spent '84-'88 working in Frankfurt, during which time I also spent an aggregate 6 months all over Turkey, from Istanbul to Diyabakir, and Sinop on the Black Sea to Adana on the Mediterranean.
Took a 2-week trip to China 5 years ago, very interesting as well, but not enough time to really get to the people. Land of extreme contrasts.
Anyway, my takeaways are 1) traveling is one of the best and most educational things one can do,
2) people are pretty much all the same, and 3) it's incredibly enlightening to see your country through other's eyes.
#3 could be a double edged sword - but it isn't. The US obviously has faults/issues, but you will come away with a different/new appreciation for this country that you may not have had before.
Highly recommend it!
