Country life gives you peace and quiet, no traffic, wide open farmlands, friendly people, no rat-race atmosphere. City life has its advantages as well--excitement, entertainment, convenience, low maintenance, lots of people and things to do.
Where you live effects everything about your life. What your day to day will be. Most people live where they have to work, where their job is. Many people have an option. I think even if we don't choose our location, it reflects something about ourselves. Some people grow up in the same place their whole life. Others move around a lot. Many people deliberately travel and want to see the world and experience different cultures, and this in a way effects who we are and who we become. Not that circumstances should sway us, but at least when we have a choice, where we live shows part of our personality.
For myself, I love being in the country because it is very laid back. I love the feeling of sitting on your front porch and looking at the fields, mountains, and wide open skies, knowing that life is supposed to be peaceful. It isn't supposed to make you feel like you have to be ambitious and busy all the time. Sure, we can't sit back and relax every moment of every day, but even in the midst of crazy activity we should be able to hear ourselves think.
Of course this can be found wherever you are. City, suburbs, country, desert island. It's less about where you are and more about who you are with, don't you think?
