Often, you can predict which meetings are going to be unproductive from the moment you get that initial email invite. There's the “planning meeting” where you hash out ideas that probably should've been hammered out earlier or the “update meeting” that could likely be accomplished with a bulleted email or the always popular “brainstorming session” where extroverts spend most of the time shouting out random ideas. Why not skip them? Have you ever even considered this as an option? Of course, some are harder to escape than others—especially if the invitation comes from your boss, a key client or a respected colleague. But there are ways to get out of a meeting that you know will be unproductive, or at least to limit the damage it will do to your productivity and time.
