``... Any fool, including an ROTC lieutenant like me, can be a military genius at the breakfast table twenty years later, after having read a comprehensive history of the battle. But real genius is the ability to grasp the essence of a situation as it is happening. To think---not on your feet but on your belly, with five radiotelephones screaming at you, men dying and crying in pain, your pants full of piss, and the thump, thump, thump of nurture rounds walking toward you.'' ---p. 118, Word of Honor, Nelson DeMille
Of course the quote describes the situation in a battle field, but I have a strong feeling that it applies to other walks of life, for example trading in stocks and options!
