He who fails to plan is planning to fail.
Plans are of little importance, but planning is essential.
I have found in my experience of war, that plans are useless, but planning is invaluable.
I'm just preparing my impromptu remarks.
Those who plan do better than those who do not plan, even should they rarely stick to their plan.
There is in the act of preparing, the moment you start caring.
Plans are worthless. Planning is priceless.
