Brief me before every meeting.
Twenty minutes before your 1:1 with Sarah, Seriesly drafts a single page. What you talked about last time. What she's been chasing across the last three meetings. The JIRA ticket she filed yesterday that you haven't read. The thing you said you'd do and didn't.
It's the briefing a good chief of staff would slide across your desk — except now you have one for every recurring meeting on your calendar, not just the board meeting.
