People tell you to focus , but never tell you what to focus on. Focus on your objective . Objective is something you can do something about it, not just philosophical. Think your objective , leave your body alone. Stay fixed on what character is thinking, then we can't lie as actors.
Actor picks an objective to show a certain feeling.
All of it is revelation. Think of your objective . Audience understands and sympathize with. Avoid everything idealistic for objective . A way to react , react as if you are saying something, like keeping your objective .
