Be open and flexible and very adaptable to change your mind very quickly. Don't believe in your ideas to the point you're married to them, always remember they're only ideas. Plans are made to help you anticipate how you'll respond to the facts over time, but reality always trumps any ideas any of us have. Meanwhile it's good to preview at the options.
