Thinking involves focusing on different aspects of the situation.
At each moment you should know what is being looked at.
Ask the question:
What am I looking at now?
You should be able to give a definite answer to that question.
In each operation (analysis, CAF, Selection, C&S, etc.) there are moments when you focus on some particular aspect of the situation.
You should know what you are looking at, and if you want to move on to a different area you should know that you are doing that.
