Meetings take a long time and often end up fruitless. In order to make the most out of a meeting, you need to 1) set an objective of the meeting, 2) make all attendees submit meeting agenda and share the collective agenda far in advance to everyone who attends it, 3) clearly designate the meeting leader, and 4) go over key takeaways at the end and set the next meeting date in order to implement what had been discussed in the meeting.
