Solitude teaches you whether your peace depends on being entertained.

There is a difference between peace and being occupied. Occupied feels fine, and it collapses the moment the entertainment stops, which reveals that what you had was distraction rather than calm. Solitude removes the occupation and shows you which one you have been living on.

Sit for a while with nothing playing and see how quickly you reach for something. Not as a test to pass, only as information. If the reach is immediate and urgent, the peace was borrowed. Building the other kind starts with tolerating short stretches of nothing until they stop feeling like an emergency.
