Meetings are like zombies, they can be a plague on your productivity. Identify the meeting that's sucking the life out of your day, and cancel it. Or, if you can't cancel it, find a way to make it more efficient. Like, maybe you can just have a meeting with just the person you need to talk to, and not the entire team.
Or, better yet, just send them an email. Trust us, they won't even notice the difference.
