In my language, we often say an imperative phrase that literally translates to "look down". It means we must see / remember that there are always people below us who are not as lucky as us, thus we should be grateful.
How do we say that in English? Is there a short phrase for that? I often hear in movies that they use the phrase "you should be grateful", but I need the other phrase that emphasizes I'm more lucky than anyone else below me.
