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.

What other people think of me is none of my business.

The script is your map of the world, isn't it? And if someone knows that if it's well-written, you get all of the beats, it will tell you everything you need to know.
