Put a song in your heart
When your mind is full of troubles put a song in your heart. A song can shift your perception when nothing else works.
I recently bought a used car. The seller was not honest in his representation of the car. I could not sleep because the old judge and victim in my head would not shut up. Eventually I found if I put a song in my heart and repeated it I was able to come to peace and sleep.
If you find yourself overwhelmed by your mind, put a song in your heart and hold your attention there.
