Nir Eyal says to-do lists fail because they have no constraints or feedback. Instead, use a timebox calendar and implementation intentions: schedule 30-minute blocks, track progress (like 3 slides per block), and adjust your estimate. The feedback loop is what actually gets work done.

One of the worst things people do that I used to be guilty of was using a to do list. A much, much better practice is a timebox calendar. Timebox calendar uses this psychological technique called setting an implementation intention, which is just a fancy way of saying planning out what you're going to do and when you're going to do it. So to do lists, because they have no constraints, are the antithesis of a timebox calendar. Because a time box calendar forces you to look at your calendar and say, okay, I can't do everything. Let's say I'm going to make a slide presentation. I'm going to work on this slide presentation for 330 minutes. And then at the end of those 30 minutes, I say to myself, okay, I worked on it for 30 minutes. And I know that the slide presentation needs to be 30 slides long. And look, I finished three slides. Well, that means I need nine more of these time boxes to finish the entire task. Now I have a feedback loop that's something a to do list never, ever gives you.
