The title of this post is a common response to simple introductions like, "How's it going?" I often give it. When I do, I think of what I'm saying as very meaningful and important. Most people don't share this opinion. Most people don't go beyond, "Well I could, but what's the point?" My feelings are otherwise.
I see these two words in the same vein as "I cannot tell a lie," or "I can't kill another human being." Of course one can do these things (in the first case one is often presented with opportunities to do so, in the second it's sort of assumed that if you're saying this you're in a situation where someone gave you a gun, possibly in an abandoned warehouse with a guy tied to a chair), the capability to do so is there, perhaps even just cause to do so, but doing so would be a terrible violation of one's personal principles. I feel the same way when I say, "I can't complain."
I live in arguable the most prosperous country on earth, and certainly enjoy a number of amenities on a daily basis. I own my own computer, have running water, and live better most kings in history-probably better than anyone alive more than 300 years ago. I find spiritual fulfillment in my faith, have a family that loves me, and am unburdened by sickness or even mild infirmities such as headaches or sore muscles. I'm grateful for these many blessings in my life. That gratitude is important. Gratitude is a key to happiness. If were to complain over trifles such as one isolated incident of a headache I had the other night or a problem on my CS homework that I thought was poorly worded I would be denying the many good things I have and failing in my gratitude. When I say I can't complain I'm saying I will continue to live a life of gratitude for the many good things I enjoy, that I refuse to focus on whatever unfortunate circumstances may befall me and instead will focus on the happy happenstances of my existence. As a grateful person, I can't complain.
