I don't know the answer to your question. I heard David say in an archived webinar something to the effect of; "If you have back to back meetings all day when do you have time to actually do the work?"
As I read through your post I wonder the same thing. I realize meetings are work...that came to me a few years ago as I do a lot of meetings. But often during meetings I am getting more things added to my list. If I never have time to do the work, my list will only grow.
Again, no answer here...sorry.
