The Effective Executive

Just started this one, so treat everything here as provisional. This is the pendulum swinging to the other side after The Halo Effect. Rosenzweig spends his whole book explaining why management bestsellers pretend to be science; Drucker never pretends. It's decades of watching executives up close, distilled into practices: effectiveness is a habit, and habits can be learned. Know where your time goes, focus on contribution, make strengths productive, concentrate on the few priorities that matter, and make decisions on principle instead of one-off expedients. That's the engineer's approach I keep gravitating to: one problem at a time, decisions made with the best available information to maximize the odds. And this is the book a lot of High Output Management was built on, and Grove aged better than almost anyone on my shelf. High expectations. I'll update once I'm done.
