“Thus 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 its 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 the sovereign.” 
― Sun Tzu, The Art of War

“Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat.”
