I found day 2 to be quite revealing! It reminded me that in all our dealings with our children, workmates, and others in general, we are creating our own environment by our approach to them.
One suggestion that would help me in these lessons is to have different colour borders around the screen in each lesson that identifies which tool and prompt is being shown. Are we looking at Codex, Claude, etc.? This would help to keep navigation clearly in my mind and avoid eating up time!
