What do I need to walk out of this meeting with?

I have a meeting about with . What I want from it: . What worries me: . Write me a half-page brief I can read in two minutes beforehand: the single outcome I should leave with, in one sentence; an opening line that puts it on the table; the two objections I’m most likely to hear, with a short answer to each; the question I’d least like to be asked, with an honest answer; and what to propose if we’re drifting with ten minutes left. If what I want is too much for one meeting, say so and name the smaller outcome worth leaving with. You don’t know these people, so say where you’re guessing about them.
