The strategy of fighting is mainly controlled by our brain.
But before our brain can work out a strategy, it needs our eyes and ears to observe our opponent’s action and reaction, basic reaction and regular reaction.
Based on these informations, our brain will make necessary analysis and judgement and finally work out a fighting strategy.
In such case, our brain is like a computer. We must feed-in much enough data before the computer can give out a satisfied answer. Same is the case in fighting.
If our observation is wrong, which is like giving wrong data into the computer, surely, the result will be wrong.
From here we can understand the importance of our observation in respect to the fighting strategy.
