tl;dr:"Operating well is a state, not an outcome." Key lessons are: (1) Reinforce your goals everywhere. (2) Focus. (3) Changing strategy feels like progress but it usually isn’t. (4) Turn up the heat in every interaction and ask uncomfortable questions e.g. What could we cut, even if it’s painful? (5) Unblock psychological barriers by asking a report what's holding them back. And more.
