Send Invites to the Party
The party, ahem, meeting, is going to go badly if the attendees do not come well-prepared for it. Send the itinerary you've prepared to other people who are to attend, and specify if the meeting is regarding issuing information, assigning work, performance reviews, or brainstorming. Thus, you ensure that everyone that comes (including you) is well-prepared for the discussion and has had time to consider solutions. Do not spring unexpected topics into the discussion.
