I love jigsaw puzzles and have since I was a small child. My great-grandmother started it with a 500-piece beauty. I got so good at them, that I figured out she had three all from the same jig. I put them together one on top of the other, matching the pieces. These days I can do a 300 piece in an hour. Not bragging, just my enjoyment of the challenge.
Puzzles are a great brain stimulator. They are also good for relaxation and to help you focus. I use them as therapy when I’m stressed.
Jigsaw puzzles and their cousins, crossword and sudoku are great tools for stress or boredom. I think boredom is just stress turned outward. Both involve some mental obsession with an overlay of rapidly random thoughts. Your mind keeps churning over and over, but you can’t find a solution. A puzzle of some sort helps you to focus your thoughts on each individual item. You are searching for a particular piece, be it shape or color, and your mind begins to zero in on that which you seek. If you allow those random stressful or bored thoughts to just whirl around in your head, they will begin to form shapes not unlike the puzzle pieces. Soon they will formulate into clues to your issue.
By giving your monkey brain something to do, you turn your subconscious or Higher Self over to the Universe to receive solutions. Not to mention, how quickly you can put that puzzle together.
