the world is flat?

Just about 10 years ago I would never imagine that I would be spend so much of my life in the western hemisphere. At that time even the thought of having a vacation abroad and taking a plane was exhilarating; but just this year, I traveled at least 10 times by plane and crossed the Atlantic Ocean 5 times; I've visited Belgium, Netherlands, and Austria during the weekends when I didn't work in the lab. Education-wise, I went to Yale, a wonderful place that I would like to call it my second-home in the last four years. I'm not bragging about anything; I just thought, wow, as Thomas Friedman said in his book, "the world is flat." Individuals today have so many opportunities. I don't know why that is, just suffice to say the world is really changing from my parent's generation; even within my short 25 years of life, I've experienced such a change. You can say the change provides unprecedented opportunities, and I'm sure I'll be shaped by such a change. Just don't know how...this is the thing I need to think about.
