If you drop assumptions, and can anticipate the possibilities, you can master the art of strategy. However, if you can only manipulate probability, you can only create a path to victory. But remember, plans can break down. The future is always a step ahead of you. The key is being able to manipulate probability and plan for uncertainty. This way, you don't have to create a path to victory, but manipulate all options so that all paths lead to a victory.
