When you know both yourself as well as your competition, you are never in danger. To know yourself and not others, gives you half a chance of winning. Knowing neither yourself or your competition puts you in a position to lose.
Sun TzuOrder or disorder depends on organisation and direction; courage or cowardice on circumstances; strength or weakness on tactical dispositions.
Sun TzuThere are routes not to be followed, armies not to be attacked, citadels not to be besieged, territory not to be fought over.
