Your brain wasn't built for 47 open loops

There is a kind of tired that doesn't come from doing too much physical work.

It comes from having too many things partially open.

The unanswered message. The project waiting on a decision. The appointment you haven't booked. The invoice you should check. The house thing that depends on another house thing. The idea you don't want to lose. The task you keep moving forward because it is never quite urgent enough to finish today.

Individually, none of these feel like a crisis.

Together, they create a background hum that can quietly become overwhelming.

I think this is why mental overload can feel so different from ordinary busyness. A full day of clear work can be tiring in a clean way. Too many open loops is tiring in a messy way. Your brain keeps reloading the same unresolved contexts, almost like a browser with too many tabs open and one of them is playing audio you can't find.

David Allen's line from Getting Things Done is still one of the best descriptions of this: "If it's on your mind, your mind isn't clear."

The useful part is that an open loop doesn't always need to be finished before it gets quieter.

Sometimes it just needs to be captured.

There is research behind this. In a 2011 paper, E.J. Masicampo and Roy Baumeister found that unfinished goals created intrusive thoughts during unrelated tasks, but making a specific plan reduced that effect. Not a vague intention. A specific plan: what you're going to do, when you're going to do it, and where it belongs.

That feels true to me. "Deal with insurance" keeps coming back. "Call insurance Tuesday at 10 after the work block and ask whether X is covered" has somewhere to sit.

A few things seem to help:

- Write it down somewhere you trust. Not a random note you will never see again. A real inbox, list, calendar, or system.

- Turn vague loops into next actions. "Figure out taxes" is a fog. "Email accountant the missing receipt" is a thing you can do.

- Do things in series when you can. Parallel work feels efficient until every project is half-open and your brain is paying the switching cost all day.

- Make more decisions by default. If it's small, decide now. If it matters, schedule the decision. The worst version is often "I'll think about it later" with no later attached.

- Say no sooner. Derek Sivers has a rule: if it isn't a hell yeah, it's a no. This doesn't work for every obligation, but it does keep optional commitments from becoming permanent background noise.

- Close the loop even when the answer is imperfect. Send the reply. Book the appointment. Archive the idea. Kill the project. A clean no is often calmer than an indefinite maybe.

The goal isn't to become a productivity robot.

It's to stop making your mind carry things that belong on paper, on a calendar, in a queue, or outside your life entirely.

What open loop is taking up more mental space than it deserves?

📚 Book Notes

Getting Things Done - David Allen

I still think Getting Things Done is one of the best productivity books because it treats stress as an information problem.

Your brain keeps reminding you about something because it doesn't trust that the thing exists anywhere else. Once the task is captured, clarified, and reviewed in a system you actually use, your mind can stop carrying it around all day.

The goal is not to become a productivity robot. The goal is to have fewer half-formed commitments bouncing around your head.

Maker's Schedule, Manager's Schedule

Paul Graham's old essay is mostly about calendars, but it also explains why fragmented days feel so mentally expensive.

A single meeting costs more than the hour it occupies. It changes the shape of the day around it. The same is true of errands, messages, decisions, and half-finished tasks. Context switching has a tax.

📝 Can guided journaling improve productivity and self-awareness?
Writing things down is underrated because it separates the task from the feeling around the task. Sometimes the first win is getting the loop out of your head.

The best productivity habits are usually boring foundations: sleep, movement, a clear most-important task, and enough uninterrupted time to work on it.

🔗 Things I Found Interesting

The Zeigarnik effect
The tendency to remember unfinished tasks better than completed ones. Useful if you want to understand why unresolved things keep tugging at attention.

Consider it done! Plan making can eliminate the cognitive effects of unfulfilled goals
The practical takeaway is simple: a specific plan can quiet an unfinished goal before the goal is actually finished.

Multitasking: Switching costs (American Psychological Association)
A good reminder that doing everything in parallel has a hidden tax. Even small switches add up when they happen all day.

No “yes.” Either “HELL YEAH!” or “no.” (Derek Sivers)
Useful if part of your overload comes from optional commitments that should never have become commitments.
