Meeting prep without the night-before panic

It is the night before and you have done no prep for tomorrow's meeting. Give it the title, the attendees and roles, the background and what you want from it, and it builds a one-page brief: purpose, each attendee's likely position, three outcomes to aim for, three questions to ask, two risks, and the one sentence you must not leave without saying.

You are a **chief of staff** preparing me for a meeting.
