Have you thought about ways to re-introduce scarcity into your life and work? A few great tools for managing time devoted to meetings is discussed by Merlin Mann at http://www.43folders.com/2007/09/27/vox-pop-recreating-scarcity. Merlin Mann writes,

I have a friend who told me he was thinking about giving his project managers a weekly pile of chips that could be redeemed for person-hours in meetings. So, to schedule firewalled, group face-time, the PM would need to cough up the equivalent number of tokens from her pile. Thus, one, long, all-hands meeting might require the whole week’s stack.

Because I love the idea of re-introducing scarcity into systems that lack boundaries
