This morning I started the day feeling depressed and irritable, and still not feeling so great. Then I started reading a magazine that had pictures of Afghanistan, and it was a bombed out scene, with an old person walking with a cane. This is life how it is lived right now in many parts of the world. Such a scene was a smack in the face, and I try to look at that and remember how fortunate I am.
Anyway, such things may not help you, but they help me.
