Understand: the greatest generals, the most creative strategists, stand out not because they have more knowledge but because they are able, when necessary, to drop their preconceived notions and focus on the present moment.
That is how creativity is sparked and opportunities are seized. Knowledge, experience and theory have limitations: no amount of thinking in advance can prepare you for the chaos of life, for the infinite possibilities of the moment.
The great philosopher of war Carl Von Clausewitz called this “friction”: the difference between our plans and what actually happens. The better we can adapt our thoughts to changing circumstances, the more realistic our responses to them will be. The more we lose ourselves in predigested theories and past experiences, the more inappropriate and delusional our response.
It can be valuable to analyse what went wrong in the past, but it is far more important to develop the capacity to think in the moment. In that way you will make fewer mistakes to analyse.
