When startling events are at their peak, clarity of vision and perspective are often lost. The smart move, in such a situation, is to withdraw temporarily, in order to gain time enough to develop a coherent strategy. This can only be done if withdrawal comes soon enough in the course of events, before the outer turmoil has muddied your inner perspective. Friends and associates may not understand the reason for your actions, friend, and may talk about you behind your back, but no great general ever plotted his strategy while mounted on his horse.
Sometimes retreating to your private tent takes more strength and courage than charging the front lines; and more brains.
