Success or failure? Hero or villain? Expert or idiot? Despite our best efforts to be sophisticated, we all tend to create overly simplistic narratives about ourselves. We do one little thing well, and we punch the air. We make a perfectly understandable mistake and we slump at the table with our head in our hands. Worse still, our assessments are often inaccurate. You now seem to be cross with yourself for what you are presuming to have been an error of judgement. But it has been no such thing, as you will see this week.
