This is probably not the best way to run a short, effective meeting, but it might be worth a shot, because here is what I know:
Every meeting is too long.
Every meeting wastes time.
Every meeting isn’t nearly as effective as it could be.
Planks are hard. I tried to work my way up to an eight-minute plank a few years ago after reading that an 80-year-old man could do an eight-minute plank.
I never got past five minutes, and that was a real struggle.
Which would make for a delightfully short meeting.
