The most important thing about a meeting is the reason for your participation. If you don't have a good reason to be there, why are you wasting your time?
Agenda
There's nothing worse than a meeting that drags on and on, because nobody knows what the scope and outcome should be. Defining them is the essence of any good agenda.
Exchange
If a meeting is not a lively exchange of opinions and ideas, it better be an email instead, because again it's wasting everyone's time.
