We work too hard, get stressed and then wonder why we're not happy. Enjoy the small things in life, the here and now because, in the end, it's all we've got.
Moving abroad changes your perspective not only of the country you move to but the one you move from. You are better able to see and understand both the positive and negative aspects of your home country. This allows you to stop being reflexively nationalistic and to become a true patriot, someone capable of loving your country while acknowledging its faults. There is no perfect place or people and there never will be. We can only strive to make ourselves and the places we live better.
