I'm sure I get the gist from just the Amazon summary: focus on the essential and throw away everything else.

Except... I need to have 1:1s with team, and I need to attend my manager's staff meeting, and his 1:1, and his weekly status review, and my own reviews, and my director's weekly meeting, and our division's weekly all-hands, and standups.

Holy fucking shit. Maybe it's just time to send my own management a note on how much overhead we're drowning in.
