The story of Britain’s rise is obvious in retrospect. It’s easy to look back and describe what happened. It’s another thing to position oneself well for it by anticipating it and seeing it happen at the time. I wonder what I would have thought at the time. I wonder whether in looking at the readings of my indicators and systems and thinking about the situations whether I would have bet well. That is why it is so important to me to have the data and the decision rules to see what I would have actually done and what the results would have been.
