Don’t try to do your best but find the good move at the tactical level which will be incorporated in Grand Strategy. The problem is not your interpretation of the quality of your move because this will be done by the Mankind itself. You are not on a Markov chain where only the present can influence the future. You need to know the past to play the best move but you need to know the future to play the good move. Your move has to be the choice of the memory of future. You are not playing your game but only a move in the game of Mankind against barbarity. So think about the metagame because in you there is a part of Mankind. You can make the point even if you feel that you are only a vertex in this network. So play your role in this struggle because it’s important.
