What I've taken away from all of this is that worrying does not serve to assist anything. Taking action does.
Remember that worry is a sly enemy, it will take control of a concern, magnify and distort it until you are no longer merely concerned but spiraling into the dark place that resides just before we reach utter fear; a place called worry.
We seem to be inundated now with books about death -- and about how great it is. I assume that this is part of the aging of the baby boomers (I remember someone quipping that we'd know the end of the baby boom had come when we started to see designer funeral parlors).
