Love these slides, hard agree on _all_ points. But, be absolutely certain on the culture before you start declining meetings, even if for valid reasons like outlined in this presentation. Declining meetings can be seen as a negative, "not a team player", thing... and, I really have to be certain on my leadership, the company, and the context before I push back on someone wanting my time. Even if their request for my time was arbitrary, or useless.

As somone who vigorously declines meetings, this gave me some extra criteria to use (estimated speaking time per attendee)

What I found the most useful was the focus that was put on having agendas for every meeting, something that I try to do for every meeting that I schedule.
