Awoke this morning thinking it might be a pretty good exercise -- just for one minute or five:
Every time you catch yourself thinking "I" (or any of its corollaries ... "me," "mine," "right," "wrong" etc.), smile.
Just for one minute.
Best I can figure, if this were a well-nourished habit, you'd be smiling all the time. And so would I. And so, even if the world continued on its sometimes-horrific courses, at least there would be some laughter.
