Someone unfamiliar with the mountains and forests cannot advance [the team]. One who does not employ local guides cannot gain the advantage.
Sun TzuBestow rewards without respect to customary practice; publish orders without respect to precedent. Thus you may employ the entire army as you would one man.
Sun TzuCarefully study the well-being of your men, and do not overtax them. Concentrate your energy and hoard your strength. Keep your army continually on the move, and devise unfathomable plans.
