Fight only the battles that you can win, win only the battles
that matter.
T"hus we may know that there are five essentials for victory:
(1) He will win who knows when to fight and when not to
fight.
(2) He will win who knows how to handle both superior and inferior
forces.
(3) He will win whose army is animated by the same spirit
throughout all the ranks.
(4) He will win who, prepared himself, waits to take the enemy
unprepared.
(5) He will win who has military capacity and is not interfered
with by his sovereign.
Victory lies in the knowledge of these five points.
