Experiencing something new is the best way to make a change. Some things are unchanging unless we experience something that will help us change.
To experience something means actually doing something. An experience can help expand our minds so we can see that there are more choices available.
When we have more choices we have more freedom to be more of ourselves. Milton Erickson wants us to discover more about our potentials and ourselves.
He wants our minds to concentrate on the vast store of experiences that we all have and learn to use them when in need and/or desire to free ourselves from the rigid ideas.
