The Magic Shell

Imagine that you are standing on a beach. Visualize the beach in your mind. Can you feel the sand beneath your toes and the warm sun on your face?
When you look around, you can see the vast, silver-blue ocean, and the sunlight sparkles like tiny stars dancing on the surface. In the sand is the most beautiful shell that you have ever seen. When you pick it up, it feels warm. Imagine you are holding the shell. What does it feel like? Is it smooth or rough?

This is now your magic shell, and you can tell it your secrets, and it will keep them.
