Like an awful lot of us, my wife and I say a short prayer before each meal. Here is my all-time favorite. It is not only a nice short prayer, but it is in my estimation a philosophy for life.
LET US RISE UP AND BE THANKFUL
Let us rise up and be thankful,
for if we didn't learn a lot today,
at least we learned a little,
and if we didn't learn a little,
at least we didn't get sick,
and if we got sick,
at least we didn't die;
so let us all be thankful.
