Too many persons involved in managing an activity can ruin it.
Origin: This is a very old saying or proverb that exists in many languages. In English, it dates back to at least the 16th century when it first appeared in print. It may well be older. There are also a number of different versions. Sometimes it’s soup, sometimes it’s stew. A similar saying is “Too many chiefs and not enough Indians.” However, as with many proverbs there are several antonyms, such as “The more the merrier,” or “Many hands make light work.”
