The thing a drama school can't give you is instinct. It can sharpen instinct but that can't be taught, and you have to have intuition. It's an essential ingredient.
That's what sets apart one actor from another, and that you can't teach. You can't give someone that. When you're working, putting a character together, or in a scene, that's where things will happen that you have to have the intuition to notice them, and to register them.
