When you think about it, the true cost of meetings is staggering. Let’s say you’re going to schedule a meeting that lasts one hour, and you invite ten people to attend. That’s actually a ten-hour meeting, not a one-hour meeting. You’re trading ten hours of productivity for one hour of meeting time. And it’s probably more like fifteen hours, because there are mental switching costs that come with stopping what you’re doing, going somewhere else to meet, and then resuming what you were doing beforehand.
