I was bad in being on meeting discipline. The only thing that consistently works: start on time, end on time, and don’t wait for late arrivals. If someone joins late, they catch up from notes/recording.
There’s a famous example from the Lucasfilm/Pixar deal: a Lucasfilm exec used to arrive late as a power move, until Steve Jobs started the meeting exactly on time without him. The exec walked in 5 minutes later and had already lost the room. And Jobs gets the deal.
It seems we're truly in a power war rn.
