“This meeting will be a success if…”
“The purpose of this meeting is…”
“The 3 things we absolutely need to get done in the next 30 minutes are…”
“We’ve gathered here as a group to…”

But, ensuring every meeting we participate in starts with quick alignment around the purpose is likely one of the best things we will do for our long term meeting effectiveness.
