If you don't appreciate what you have 24/7 and are not grateful for it what would happen if you were to lose it?
Some or maybe many folks are too busy complaining about what they don't have to notice and appreciate what they do have until it's gone. Guess what? It's way too late then.
Why not appreciate your country - what your country has to offer - rather than complain about it and wanting to change it? Because once its gone - as you write - its gone.
