"Idle minds are the Devil's workshop"

I was watching "Call It What You Want", a video by Foster The People and saw that quote. I figured it came from someone else so I've been searching and found this:

There is a set of English proverbs that are worded similarly:

• Idle hands are the devil's workshop
• Idle hands are the devil's tools ("Collections" 1808)
• Idle brains are the devil's workhouses (T. Fuller 1732)
• An idle brain is the devil's workshop (H. G. Bohn, "Hand-Book of Proverbs," 1855)
• If the Devil finds a Man idle, he'll set him at work (J. Kelly, "Scottish Proverbs," 1721)
• The devil finds work (or mischief) for idle hands to do

"An idle brain is the devil's workshop" is actually from the "Hand-Book of Proverbs" H.G. Bohn. 

I was thinking about stuff that will happen to me sometimes. 

I’ll be sitting at work. Alone and its quiet. I’ll get random thoughts bouncing around in my head. Usually they are harmless random stuff. Sometimes I’ll hear the Holy Ghost telling me something or prompting me to do something. However, the thoughts are not always benign.

Occasionally I’ll get loud negative thoughts in my head. With words to try and stir insecurity, disbelief, doubt, and dislike. That was happening on Monday night, 12/5/11. Its stuff that I used to get wrapped up in and sink. I’m not as susceptible to them now. They are very loud, overshadowing quieter thoughts, obnoxious, hard to listen to. It takes work to tell it, no you’re wrong. I’m thankful that I can tell the difference now. I’m thankful for the strength that I receive to dispel the negatives and not fall to them again. There is no way in the world that I want to become wrapped up in despair again and sink to the bottom. Now that I’m a member of the Church, I can receive help from the Godhead to help keep me up and out of that lake of fire.

More reasons I’m eternally grateful that I joined the Church!

In the name of Jesus Christ,

Amen
