And that is a phenomenal step. One that needs to happen. But one that needs to happen in conjunction with an even more monumental shift.
Change the start time of meetings to something “weird”.
Don’t start on the hour or half hour. Don’t even start on the quarter hour.
Start at 10 past or 10 til, and go for 15, 30, or 45 minutes – with a hard cut off. Just like college classes. Oh – and just like class days when all you had was a test, as soon as your part of the meeting is over, leave. You may have to wait to leave until the end. But once your piece is done, just like when you finished your test, walk out and get on with your day.
