I think it's just information overload. There's so much information everywhere now clamoring at you for attention. Our brains aren't made for processing this much information. Going on a media diet helps. Going completely offline helps even more.

Something I do when I struggle to focus is to add different stripped down user accounts to my computer.

I wanted to dabble in rust so I added a user called ~rs that literally only has access to two application hotkeys (via niri). super+enter opens a terminal, F1 opens the offline rust documentation. Yeah I can just log out and scroll HN, but there's a enough friction to that, that it doesn't really happen very often.

> I think it's just information overload. There's so much information everywhere now clamoring at you for attention. Our brains aren't made for processing this much information. Going on a media diet helps. Going completely offline helps even more.

I wonder how much is real information, i.e. information that truly is related to your life, interests and within your sphere of influence; and how much is just noise that camouflages as information.

wormpilled•9m ago
That's a really cool technique.

> Yeah I can just log out and scroll HN, but there's a enough friction to that, that it doesn't really happen very often.

You can make sure the friction is high by having your password be something difficult to remember, written down on a note, and keeping that note somewhere "out of reach".

The author doesn’t mention it, so it seems appropriate to suggest asking a doctor for attention deficit disorder screening. The cultural forces in play encouraging us to flit and switch constantly are a perfect distraction from the possibility one’s own brain is complicit.

I would caution a little against the prevailing wisdom of diagnosis-as-panacea. I've had a diagnosis for most of my life, but never seen stimulants as worth it (admittedly I've not tried them long term, but that's because after reading a whole lot about it I don't want it in my body). I don't think the diagnosis changes anything for me other than that. It's very much a case of "now what". I suppose some people find a great weight lifted from their shoulders at the idea others struggle with the same thing, or that their struggles aren't due to a personal failing. But I can't escape the next step which is that you still have to do go out and do all the same stuff anyway...

ADHD isn't something you suddenly develop at 30 or 40. You can get diagnosed later, but the signs are meant to have been there since childhood.

People often question me how I manage to focus for more than a few minutes and I'm always confused because back in the day I was constantly informed I didn't have any focus and needed to be treated (adhd).

I'm not convinced attention spans themselves have changed; I think it has more to do with the fact that people's brains aren't defaulting to daydreaming anymore when bored.

I think it's still an issue with people being addicted to phones because I'm sure the lack of daydreaming -- which studies have proven as beneficial and arguibly even a form of microsleep -- is likely causing a lot of the fatigue and inattention people feel; as in their brains are literally being deprived of a natural thing and so are exhausted because of it.

(as an aside: whew what a run-on sentence i have no intention of fixing)

My personal supposition with 0 proof is that the "gen-z stare" is the end-stage of this phenomenon where after being deprived of daydreaming for so long they are essentially "sleeping while standing up" as it were.

oggreen•42m ago
That's a very interesting perspective but now that you mention it, I can't even think of the last time I daydreamed, even when I'm not on a device. Curious if phone usage or whatever doom-scrolling we do exhausts the same part of the brain that we use to daydream.
embedding-shape•39m ago
That's interesting. What happens if you just sit there doing nothing, looking around and what not? Does your brain start to wander by itself?

Personally I struggle to remember any day I haven't had at least 10-15 minutes of idle time doing nothing, just thinking idly, but I still have similar struggles as the author. Although I barely use my phone for things neither.

TheLML•24m ago
I sometimes pause shows or YT videos I'm watching just to daydream for a little bit about something that just crossed my mind. Additionally I go outside at least once a day to walk or ride my bicycle, which also helps with this.
Zealotux•45m ago
Yes, I feel like my brain is fried by dopamine dispensers, it's very bad and I have no clue how to get control back. At least I have some healthy routines in my days but it really does feel like being addicted to a hard drug.

I can focus at home. I have a terrible time focusing in the open office floor plan at work. I have to wear noise-canceling headphones just to cut down on some of the noise. Even then, people are constantly stopping by to chit-chat or make small talk. I hate it.

Claude Code has made my computer as - or even more - addicting as social media.

I created this for me https://rainbreak.franzai.com/ to force myself into a break. Into breaking out of the agent loop.

  7 minutes for short, 21 for a long break.

Strangely I think it's why I like roadtrips so much. Sitting doing absolutely nothing for even 15 minutes is difficult for me, but I can drive for hours doing nothing but watching the world go by, even without music or podcasts on, and it's fine. And that feels good.

Living in Seattle saved me. In the winter months I started waking up and sitting in front of a SAD light for half an hour. I almost immediately got bored so I started reading long-form books (with the occasional short story) in front of the light for an hour each morning.

I gave up on facebook in 2010 and twitter in 2020ish. I never developed the habit for other social media. I turn off slack and email for the first 45 minutes of each hour. If the server is on fire, call me. That's why I have a phone. Oh, and I have an old-school non-smart phone for phone calls and it often lives in a different room from where I work. I run a TOTP authenticator on a tablet that's not configured to receive any messages.

HN and an occasional YouTube video are my only online distractions. In my advanced age I've lost the desire to tell everyone how wrong they are, which seems to be the national sport of online comments sections. (Though, HN, you're much better than most places.) I've been getting into GMRS lately and it's hard to turn off the radio during work days, but I have been able to do it. Maybe I should write a similar article saying "the net doesn't distract me, but dang if I can't go 10 minutes without thinking about people I know via GMRS."

The author of this piece makes an observation about bullshit vs. attention that is probably worth looking into. My last several jobs have included less bullshit, but a lot more documentation. Which is to say, the docs I write seem to have actual applicability to a real business problem and it's solution. There's little busy work that only serves to prove that a remote VP has more people working for him.

I think what I'm trying to say is a) it is possible to strengthen your attention gland. I'm happy to see the author at least trying. And... b) maybe there's a correlation between perceived bullshit and ability to focus. This needs more research.

Regarding the urge to “check what’s out there”, one simple rule I follow is: spend around an hour in the morning catching up with HN, a few reddits, a couple newsletters, and Bluesky. I completely avoid Twitter/X and LinkedIn, trusting that anything significant enough bubbles up to those other places.

Most important — do NOT check any of those the rest of the day.

Advice that works: - Watch the Robert Sapolsky human behavior lectures.

- Learn about basic neuropsychology, to at least have a working understand of the triad Default-Mode-Network, Salience-Network, Executive-Network.

- Watch your ambient CO2, also at night.

- Sleep so that you always wake up with no alarm.

> That's a very interesting perspective but now that you mention it, I can't even think of the last time I daydreamed, even when I'm not on a device.

Sometimes I just turn my phone off and stare at a white wall for 15 minutes. People made fun of me when I told them how relaxing I find white walls, but it seems it turns out, that I'm not the only one doing this?

graemep•21m ago
I agree. I am not sure it is as similar to sleep as you claim, but its definitely good for your brain.

I say something similar in the context of parenting, that a reasonable amount of boredom is good. I think it likely that being constantly entertained makes people more prone to seek constant stimulation.

This did not start with phones either. I am Gen X and it happened in my childhood with kids being dumped in front of TVs. One difference was a lot of adults resisted this and limited hours in front of a TV, whereas now a lot of adults are addicted to phones too.
