Hi. Please correct this. This is a made-up bio (biography) or self-introduction. This is writen as a writing exercise. Let us assume that "XXX" (three X's) is a country.

I was born in XXX. Our familiy moved to America in the year xxxx. Since I had finished middle schol in XXX, I enrolled in high school as a freshman once we got to a city in America. After completing the high school education with good grades and a high class ranking, I went to college. After graduating college with a degree in XXXX, I spent some years in a restaurant as a manager, and, with some good luck and hard work, I eventually moved up to be a corporate executive. By then, I had two wonderful kids, a lovely wife and a nice home at a suburban neighborhood. Then, in what could be called a bad case of middle-life crisis, I decided to leave my job and family to travel to Europe with a backpack. With a little money on me, I first went to France and then travelled to just about every country in Europe. After a year travelling, I came back home in America. Now, I am home, working for the same corporation.
