I let my intuition guide me for there is no fear in this still little small voice.

There's a reliable tell between the two. Anxiety is loud, repetitive, and always about the future. The other voice is quiet, says the thing once, and is usually about right now.

Notice it in ordinary moments — the small unhurried sense that you should call someone, that this room isn't right, that you made the decision days ago and are only waiting to admit it.

That voice never raises itself, which is how it loses to the shouting nearly every time.

You don't strengthen it by concentrating harder. You strengthen it by making the room quieter, then acting on it once, so it learns it gets listened to.
