What we eat is the one simplest way to declare who we are - the table reflects our values with a clarity that few other theaters of human behaviour posses.
The approach and strategies are very similar in that you gather all the information you can and then keep adding to that base of information as things develop. You do whatever the probabilities indicated based on the knowledge that you have at that time, but you are always willing to modify your behaviour or your approach as you get new information. In bridge, you behave in a way that gets the best from your partner. And in business, you behave in the way that gets the best from your managers and your employees.
In my opinion we learn nothing from history except the infinite variety of men's behaviour. We study it, as we listen to music or read poetry, for pleasure, not for instruction.
