No battle plan survives contact with the enemy.
One cannot plan for the unexpected.
We can't simply blame the engineers when things go wrong because, no matter how well they plan, things don't always go according to plan.
A plan is only a scenario, and almost by definition, it is optimistic... As a result, scenario planning can lead to a serious underestimate of the risk of failure.
Planning is like taking on blinders. I think it is a wise thing to be open to whatever shows up on your doorstep.
I've never been someone that's had a five-year plan, or a three-year plan. That just seems to lead to a lot of disappointment, and doesn't give you the chance to be flexible.
I've been taught in my life that you can have plans, but you can't count on them.
We certainly will prepare consciously and professionally, but still you cannot predict the future.
That's why I hate the outlines and treatments, because all you get are cliches. If you put things down on paper as your plan, it's very hard to get those ideas out of your head and do something better.
Today, if someone showed me a five-year plan, I'd toss out the pages detailing Years Three, Four and Five as pure fantasy Anyone who thinks he or she can evaluate business conditions five years from now, flunks.
You can make a board for all the goals you want in your life with the pictures on it, and that's great, daydreaming is wonderful, but you can never plan your future.
I think there's a limited amount of planning you can do, at least in the position I'm in. Maybe more successful actors can plan more than I'm able to.
Unless you are a fortune-teller, long-term business planning is a fantasy.
Humans are the only animals that try to dwell in the future. You don't have to purely live in the present situation without a plan, but the future plans you make can only be based on the aspects of the future that manifest within the present situation.
