It's one of those things that seems obvious but you know you wouldn't have thought or written it. I can visualize other people at work over reacting now and laugh at how weird it would be. I'm also picturing my trading with a loss or stop out or mistake and not taking it hard any more. I'm also realizing that I already know this in all my other occupations. IT, Music, Art, driving, etc.
The guy is good, really good.
