Trip over your own tongue. Don't be a tongue tripper. If one gains control over the tongue, he controls himself in all other areas of life too. If I lose control of my tongue - gains in other areas are diminished. For out of the overflow of the heart the mouth speaks.
Words usually lead to deeds.
Poster - Loose lips sink ships. Also wreck lives. The tongue is a window into the soul. The tongue can do great harm. It does damage out of proportion to its size .
