I have heard of that saying. I guess it means
be thankful for what you have and not complain about what you don't
have, yet. It is like looking at a donut and complaining it has a hole
instead of just enjoying the donut.
Sheesh and ther I was thinkin the hole was cool.
I understand the point of the message but I get a funny unrealistic vision of a person without feet which makes me laugh. Maybe I'm just evil.
