You're an Editor, Not a Writer
Rabois's central metaphor: the best operators act like editors, not writers. Writers generate the raw material. The editor's first job is the red pen: simplify. Cross things out. Strip every initiative, every plan, every product down to its essence.
Simplification is not dumbing down. Complicated instructions don't survive contact with a growing organization. If you can't explain the strategy simply, a hundred people can't execute it, and a thousand definitely can't.
A useful self-test: track how much red ink you're using. Early on you'll edit heavily. If months later you're still rewriting everything your team produces, either you hired wrong or you never taught them your standards. The amount of editing required should trend toward zero.
Key idea
Manage with a red pen: relentlessly simplify what the team produces. If the volume of editing you do isn't shrinking over time, something is wrong with your hiring or your teaching.
