I've always heard that alcoholism is a disease of perception. For example, when I first got sober I kept hearing that it was a disease, but I never really saw it that way. Once I started to work my program and learned more about it though, I began to look at it differently, and sure enough it changed! I now see it as the disease it is. As I continued to work my steps and recovery, I began changing the way I looked at a lot of things and they, too, began to change. For example, my past used to be a source of shame and regret, but when I looked at it as a source of experience, strength and hope that I could use to help another, my feelings about it changed as well. Looking at it this way, I gained a new appreciation for it and my very past seemed to change as well. Today I know that every situation in life is open to interpretation depending on how I choose to look at it. To help me gain perspective, I sometimes pretend I'm part of a debating club and have been assigned the task of building a case for the opposite point of view. Forcing myself to look at something differently changes my opinion and, seemingly, the thing itself.
It always comes back to how I look at things. Once I change that, everything else changes as well.
