On Planning, On Meetings

Sit in an all day meeting and realize how much work you could have gotten done.  If you can't cancel or leave the meeting, you've got to make efficient use in it - but how?...besides intermittent iPhone e-mailing, the obvious answer is brainstorming for another project/task; prioritizing to-do list; and then the obvious 'actively day-dream'...I would refer to this as a combination between active listening and day dreaming.  Greatness ensues. But don't do too much daydreaming...
