Planning is part of life.  If we do not plan our life, the life around us will control our actions.  I plan for success and for failure, for victory and defeat.  I look to every possibility I can conceive of, and plan for them all.  When something happens that I have no plan for, I simply follow the closest plan that will work in the short term, and make new plans for the long term.  For me, there is no life without a plan.
