"You get so used to a world that you complain, but never actually want anything different. Why crave the unfamiliar?"

Most people do not realize that as they continue to find things to complain about, they disallow their own physical well-being. Many do not realize that before they were complaining about an aching body or a chronic disease, they were complaining about many other things first. It does not matter if the object of your complaint is about someone you are angry with, behavior in others that you believe is wrong, or something wrong with your own physical body. Complaining is complaining, and it disallows improvement.
