Why it Works
Be the Boss - Worry and stress like to be in charge. They make a narrative that plays on repeat in your head like a nasty earworm, and this hijacks the rational thinking part of your brain. Worriers have great imaginations and this can be harnessed to help you respond to worry in a different way.
Make Space - By using imagination to visualize the worry voice, you distance it from yourself. When you have that space you can put it in its place.
