I came across this image on Facebook. As hokey as it is I think it makes sense. It's a good reminder for me...but alas some things are easier said (or read) than done. None-the-less, it still moved me. At any rate I thought I'd share it. (Click for a slightly larger view.)
My attitude is much like your posting.
Enjoy every day, never eat alone, share your good fortune and don't pass by a hungry person without offering to by a meal of some sort.
