The funny thing is, the answer to:

> Why This Actually Works

isn't anything the author lists under that heading. It's actually what he says above:

> Every night, I check tomorrow’s calendar. I dump everything into the next day’s section. Scheduled items get times in front. Sub-bullets hold notes or reminders. Finished tasks? I delete them or add what happened. Still on the list? Not done yet. That’s it.

That's why it works. He can build a simple ritual around it. The medium doesn't matter. The ritual does.
