Slightly Shorter Meetings
A few jobs ago, as the number of daily meetings increased, I picked up a tiny meeting tweak that I’ve carried with me and deployed at each place I’ve worked since. End all meetings five minutes early. Instead of half past, end it at 25 and instead of on the hour (complex maths ahead) end at 55.
My reasoning is simple and selfish, I hate being late for things. This approach gives people time to get to their next meeting.
