I have a saying, "It could be better, it could be worse. Not much of a system of measurement is it?"
That pretty much sums up life. My life could be better (by a lot!), or it could be worse (also by a lot), but in the same vein everyone's life is like that. If life is poopie for someone else it really isn't a measurement for my own life, in the same way that if life is roses for someone else it is their life, not my own. Not my perspective, not my wants, not my needs, not my hopes, not my fears, not my desires... not my thoughts.
