Most productivity advice is written for people who do tasks. Knowledge work isn't tasks. It's states: orienting, exploring, synthesizing, articulating. None fit into a 25-minute Pomodoro.
Generic systems assume work is fungible. They treat "write report," "write code," and "write strategy" the same. But these require entirely different cognitive modes. A system optimized for one will fail the others.
The real skill isn't focus. It's mode-switching—knowing when to stop executing and start exploring. When to stop exploring and start deciding. No productivity system teaches this because it's not a system. It's judgment.
