1. Ask the meeting organizer if you're needed and why. You'd be surprised how many times meeting organizers just want to include everyone, and don't actually need you.
2. Ask for an agenda from the meeting organizer beforehand. If there isn't one, skip it. Meetings without an agenda before hand have a low value in general.
3. If you're not necessary for a meeting, consider skipping it and reading the notes afterwards.
4. Ask if the meeting will be recorded, so that you can time shift your viewing of it and watch it at 2x.
5. If someone schedules a meeting with you, ask what the question they're trying to answer is beforehand, and if you can reply to them by email, or ideally send them a document or FAQ to refer to - success! You've managed to remove the need for a meeting.
It seems like there should be a way to have a platform take on a custodian role, but under your direction.
