"A Satisfied Mind" is a country music song written by Joe "Red" Hayes and Jack Rhodes.
I put a lot of thought into the song before I came up with the title.
One day my father-in-law asked me who I thought the richest man in the world was, and I mentioned some names.
He said, 'You're wrong; it is the man with a satisfied mind.
'"[1] The song has been covered by a variety of well-known artists.
