In England, when they caution you about a potentially dangerous step, the sign reads: Mind the Step. If it's a low overhead that demands caution, the sign reads: Mind Your Head. They use the word "mind" in the sense of paying attention.
We need to use the term "mind" in the sense of obedience. "Mind your
mother" we were told as children. In that same sense, we need to say,
"Mind your head." So many today are saying, "Follow your
heart." That can cause a lot of grief and get you into plenty of trouble.
You will be a lot happier if you mind your head!
