Things I've Learned from Traveling Around the World for Three Years

In general, the best piece of advice I've received is simply "do as the locals do".

The 'culture shock' between Toronto, Ontario -> Montgomery, Alabama won't be much different than if you were moving from Los Angeles instead. In contrast, the culture difference between Toronto, Canada -> Cairo, Egypt or Bangkok, Thailand will be pretty danged huge.

Contrary to popular belief, people around the world are good. They are willing to help you out and are less likely to take advantage of the fact that you are new there. There is also a sense of curiosity - about who you are, where you are from and what you think of their lands of origin. It often gets a little tiring answering all those questions. :)

On the other hand, governments and officials especially in third world countries tend to be corrupt and agenda-driven. It's amazing how much money changing hands can do, and this I believe is a big deterrent to foreigners in many lands. You need to be a little street smart and know how to work your way out of a potentially sticky situations.

I agree with other comments on HN that you need to be careful of germs. I spent a year in the US before heading back to India to visit family, and I had food off of a street-vendor. I was sick for the next 3 days (God help me now that I have been here for a decade :D). Living in a very sanitary environment like the US can (potentially) weaken your immune system [1]. Ensuring that the food is sealed, or at the very minimum hot is a good way to avoid some of the pitfalls. On the other hand, I have eaten at locals homes in Nigeria, and don't remember having any issues (it's been a while since I was there).

This article makes me want to drop everything and take off for a few months. Sadly, that won't be happening anytime soon. But if you were to take away one thing from this article - it is that you should travel. Going to most countries in the world does not have to be expensive, and it will give you a good way to find out about other cultures, and potentially give you a new avenue into your own [2]

[1] - I am not a doctor, but this has been my experience. I tend to be susceptible to unclean water and food - even the pollution in big cities like Bombay affects me way more than it did when I lived there.

[2] I was raised in a western culture - watching NBA and CNN, listening to pop and rock music, and reading Archie and Mad magazine. But after coming to the US, I have come to realize that there is a lot of things the Indian and American cultures have in common - even more, that there is a lot they can learn from each other.

"The media lies" is something everyone should take to heart. It's an astonishing thing to be in a place where the #1 story of the day is happening and not see anything even remotely representing the reporting on it at ground level.

Also, as an American, I can vouch for "people don't hate Americans". Individual people may be rude, or behave poorly, but they're likely rude and poorly behaved to everybody. It's amazing how that one simple act of understanding can completely change the lens you view the world with. There's an old American adage that the French (Parisians) are rude to Americans. Not so! Parisians are rude to everybody, it's just like New York! If you understand that, and get into the vibe, places with rough social interactions like Paris or New York actually become very navigable and pleasant.

And finally "Everyone should travel". I can't express this enough. There's absolutely no substitute for actually spending time in a place. Reading about the Urals is one thing, eating dill laced food from local farms everyday is another. Talking about how South Korea is modern but different than the West's version of modern is one thing, taking the Seoul Subway to a Korean bar and meeting up with a dozen friends for a night of laughter, drinking, eating and otherwise having a good time is simply a different kind of experience than doing the same in the states. All the broad brush strokes are the same, but the particulars...the texture of the event...are all different.
