What if all negative thoughts such as greed, envy, jealousy and anger were inspired by some form of defeat, failure or neglect?

When one does not use the brain for the expression of positive, creative thoughts, nature fills the vacuum or space by forcing the brain to act upon negative thoughts. ~Napoleon Hill

From Proverbs 16:27-29:  Idle hands are the devil’s workshop; idle lips are his mouthpiece. An evil man sows strife; gossip separates the best of friends. Wickedness loves.
