I don't understand this blog post at all. It seems to only show the very tip of the situation because, based on the text alone, the story/situation doesn't add up. Especially the part where he says he was doing everything perfectly for the week, yet everyone still wanted him gone. It seems like there was a much deeper personality conflict or something we aren't seeing. Maybe this is my fault, but unfortunately, it also makes the lesson/point a lot weaker and more muddy.
Seriously one of the more confusing blog posts I've ever read.
