First, just in time manufacturing has the noted weakness of having no slack or resilience in the system. This is part of why we experienced supply chain disruption during the pandemic.
Second, it is assuming that knowledge that's not being 'used' right now in production environment is useless.
For example, the way people avoid scam and snake-oil medicine is not by directly knowing every single piece of science but having a broad knowledge enough of the world to know that it's probably scammy. I don't need to know much about virology to understand that drinking bleach is probably a bad idea for fighting viral infection.
Third, most of what he's going to read is probably not real knowledge, or difficult to obtain unless experienced or acquired directly. Some things you can only learn via doing. Some things you can only learn through systemized research. How many of these books about entrepeneurship only apply to their specific situation, or specific context? How many are simply scam?
What I think is helpful, however, is to cultivate curiosity about the world, in all things that you can. It's probably helpful to your career if you focus your curiosity on specific things you need to do, but that's not the only thing worth learning. I think I want to focus on things that make me a better engineer and build a successful business, so maybe 60-70% for that, and the rest for play and passion and just love of learning.
Edit: added a missing no as pointed out by someone.
: Over the next 6 months, I read 30+ books on entrepreneurship, startups, marketing, “growth hacking,” and everything tangentially related I could find. And that doesn’t include the countless blog posts, articles, reddit threads, and whatever else I could get my hands on.
: A good plan, right? No, 80% of it was a waste of time, and most people make the same mistake with how they consume information every day.
Well, yes, because a great deal would be repeated even on tangential subjects as the authors aren't necessarily assuming you've read anything else on the topic.
and here:
: Getting in shape requires doing a few very simple things every day for months, not finding a new 13 minute 6 step workout every day so you can have a butt like today’s hot celebrity.
No, but it may take experimentation and reading to find a routine that works for you.
: You don’t need an entire site on lasting longer in bed or water fasting, you just need one or a couple really good articles.
Again, people vary. Why not cover them all, and the unforeseen events, instead of just outputting what worked in your particular case as if you're everyone?
And that is true in most fields. It takes seeing multiple perspectives to figure out what will "stick" with you. Tiago Forte's "Building a Second Brain" stuck with me because I had already read "Getting Things Done" and a number of other productivity books. (As but one example.)
: A good plan, right? No, 80% of it was a waste of time, and most people make the same mistake with how they consume information every day.
>Well, yes, because a great deal would be repeated even on tangential subjects as the authors aren't necessarily assuming you've read anything else on the topic.
I also read a lot of these books and I can confirm that 70-80% of the content is unnecessary. It's mostly the author boasting about how great they or their methods are and stories about someone who implemented the method successfully. It seems that every book has to hit 200/300+ pages mark. Most of the content is just filler.
Did you mean 'having no slack or resilience'?
Assuming you did and I understand your point, I disagree with it insofar as it applies to knowledge. Yes, JIT manufacturing of real things can be easily tripped up and it screwed us during the pandemic, but does that apply here? The author is saying "when you figure out what you need to read, go out and get it" rather than "keep a bunch of tabs and bookmarks hanging around in case you need them".
I mean, yeah, I guess if you only read things you can get from the library or in dead tree form, but if you really want to read something there's ebooks and audiobooks galore out there, and if we have a supply chain mess that's so bad that you can't get an electronic book, we're all kinda screwed anyways.
I am an advocate of learning broadly, instead of being narrow. That's not to say you shouldn't learn only the things you found that you need, but that it shouldn't be the only thing you're doing.
Books, I assumed, will be there if you need it.
The just in time example is a great example of why you need to read broadly. If you read about logistics about the pandemic, you would have learned about the weakness of just in time.
Self-help books in general (and entrepreneur porn books in particular) are notoriously thin on substance. It's no wonder that most of this was a waste of time. It's like saying that eating is a waste of time because once I ate nothing but peanut m&ms for a whole month and found that most of the calories were unnecessary for survival.
Most of these self-help books are made because publishers can sell them, mostly on the name of the author.
At the same time, most authors could condense their “insights” into a 3-4 page article. The issue is publishing a 4 page article is not profitable, there’s too much fixed cost, and too little market price to absorb it.
The logical result is publishers that insist that a book must be extended to ~300 pages to be really profitable, and authors that pad their books with cherry-picked examples, anecdotes, “case studies”, and whatever else they can to get the book published.
Self-help books could try having shorter ebooks. They would have to forgo printed copies since pamphlets don't work in the store.
It’s like kissing in 6th grade.
You can read all you want about theory and technique and tongue placement, but you don’t know shit until you’ve done it yourself.
Don't try a good one or you'll fall asleep at 4am when you finish it.
You mean 4am two days later, when you finish the whole 12-book series that begin with the book you picked.
Don't ask me how I know.
Get your room cool, dark, and quiet
No caffeine after morning. No alcohol in the evening. Cleanup your diet.
Quiet your mind. This isn't just an "at night" thing. In my experience people who lose sleep worrying are the same people worrying all day. Try therapy as needed.
Screen time hasn't really impacted my sleep, but I don't have any social apps on my phone, period. Listening to a podcast or reading (on the phone, with "night mode") never seemed to be an issue.
Exercise regularly, whenever works for you. Moderate/Zone 2 is a good place to start.
I've probably forgotten 95% of everything I've ever read. But I certainly don't feel like all that time was wasted.
I think that's covered under "entertain you".
George Dyson has what I found to be an enlightening metaphor for how our relationship with information has changed. It is repeated here: https://edu.blogs.com/edublogs/2010/01/george-dyson-media-li...
It's not even rude it's just reality. This post is 1 in a billion and it isn't written very well nor does it really give you anything new. Putting it up next to historical philosophy it's definitely the potato chip of blog posts.
I have decided to eschew any learning and stick with "Me big caveman. lift big rock get stronger" approach and it's working fine. Taking it easy, enjoying it, and not worrying too much about anything else.
It's more refreshing to REFUSE information than to consume it.
"Thats a whole lotta words, to bad I ain't reading them"
I did something similar when I was powerlifting. Basics worked very well. I'm also doing the same thing as I learn jiu-jitsu. There's so much crazy stuff on social, but much of it is for show. And, to get good at something takes time. If someone is trying a new move every week they are never really getting good at anything.
Though there are several reasons to agree and disagree with the author, the thing that's been left out of the comments so far is that: making connections between ideas is absolutely essential. It's not that I strictly need to know the things I know, but the ability to draw on a variety of mental resources from a variety of fields is what makes me useful and exceptional at my job. Given that the author readily admits to only having interned at a major company once and is now looking to start their own business is the big giveaway that they lack the life experience to be able to apricate the difference between data, information, knowledge, and wisdom. This is not shocking, most young folks are eager to rise up in the world and are sick of school, but, if I could give some unsolicited advice: keep learning. When you stop moving, you'll notice that the world stops moving around you too. It's the ability to draw connections between unrelated ideas that makes creativity and innovation possible. If you only have a few ideas in your head, then you are absolutely impairing your ability to think. Similarly, if you become too fixated on, well, anything... than you're going to miss the big picture. Outsourcing your mind to Teh Internets reduces your mind to only that which can be google'd, and even if that's acceptable to you than you still have to know what to put into that search-box.
If you feel like 80% of what you read is a waste of time, just, erm, don't do it.
So if you have a project, then first consult with different people, I would also consider that "just in time".
It's interesting to think about how much wasted energy comes from tabs you're leaving open, hoping you'll get back to them one day.
I can still remember when having more than one window in the browser was first possible and how cool we all thought it was.
"Tab hell" is hell on earth. It also makes you mentally ill.
The biggest issue with leaning into just in time reading is you absolutely miss out on knowing whether to pay attention to something.
HN is a big part of that, I can read about a wide array of technologies and processes and science that I normally would never encounter. And without fail, some number of those topics will come up in work conversations and I can speak somewhat intelligently on the topic.
The same is true even for fiction. Having read some semi-obscure book long ago may be a connection I have with a new acquaintance.
Again, a lot of it is wasted, it there’s no way to know exactly which bits will never come up, and which will.
I do however, agree with the article in that you should actively choose what you read, instead of having content pushed towards you.
> "Anything you could possibly want to learn you could figure out the basics of in an afternoon with a WiFi connection. You don’t have to worry about front loading everything because you’ll hardly ever be in a situation where you can’t look up the answers."
Once you get past the educational phase, in which teachers present you with problems to which they have answers written down somewhere, you enter the real-world phase, in which you have to come up with and test the solutions yourself, as nobody has them written down anywhere. That's when already having a working knowledge of similar problems and situations will be of great benefit, particularly time-wise.
> The school model focuses on just in case knowledge.
Take my math education, for instance, I may have wasted a bit time on all kinds of trigonometry tricks and way too much time on conic sections in the analytic geometry classes before learning calculus. But "focuses on just in case knowledge"? Really? What else is really wasted? Most of my math concepts are inter-connected and I used them directly or indirectly on a daily basis. Given range and depth of our education, we really just learn the minimum concepts.
If I needed to do something I was much more effective when I learnt "just in time".
But I had no problems building a web/full stack application when I was 13, despite nothing really preparing me for it.
For most things especially in times today, all you have to do is Google and/or combine Google with GPT.
I've learned much more coding and actual real life problem solving than I learned in school, because it's much more stimulating as an exercise.
- Systems. Yes, you can read papers and case studies and what not. But it will not be easy for one to even tell which part of a paper is the essence, which paragraph needs deep dive, or which claim needs close examination. In a seminar, a professor will work with students to critique papers, to cross examine multiple systems on related ideas, to deeply understand the theoretical bounds and the practical implications, and etc. That kind of experience is just not easily available in other places. Besides, it's just miles easier for someone to tech Lynch's book on distributed algorithms, for instance, with properly designed hand-outs and homework than reading the tomb by oneself. Similarly, it's not that easy to grasp the idea of program analysis if one wants to get in the trench of writing a compiler backend. I got seriously confused in an introduction course on program analysis for all the concepts about lattices, partial orders, abstract interpretations and etc. It's hard to imagine that I'd have the same access or even energy to study such stuff out of school.
- High-dimensional stats and probabilities. Again, I'm sure a brilliant student can teach herself, but man, even finding the right accessible material can be hard, let alone digest the fundamental ideas and concepts in such readings without the help of my professors and classmates.
- Math, all kinds of math. I'm not sure about you, but math matters in software development. Understanding temporal logic and mathematical logic in general makes doing formal verification much easier. Understanding probability and queuing theory enables me to test and diagnose my systems at a whole new level. Understanding combinatorics makes it really easy to learn data structures and algorithms rigorously. Understanding formal reasoning in general makes it easy to follow the books and papers on distributed algorithms. Linear algebra and numerical optimization and calculus are also important but hard to learn by oneself if a person wants to tap into ML sys.
Besides, even the fun of studying STEM topics is hard to get outside of school. I'm sure one can read about physics and chemistry and what not, but man, having labs and professors who can give you guidance... That makes a whole world of difference.
And the phrase they used was a shift from “just in time” logistics to “just in case” logistics.
So this is the first time I’m seeing this phrase and now this article uses it again.

The reason read-it-later apps exist is because we want to buy the insurance policy that IF there is a future situation in which the information is useful, we have it saved somewhere to access it.
The reality is, even if you have saved it at some point, there's no guarantee you'll be able to remember the knowledge when you need it.
This is precisely the problem I'm building a solution for.
The problem with this is that having information that you don't necessarily need can actually help inspire you and increase creativity. If you always rely on having a specific question first, then you are limiting what you are exposed to. Not necessarily bad, but not good for more open-ended work.
Interestingly, this author follows that.
"If it doesn’t answer a specific question you’re currently asking, then don’t read it."
I almost never read for entertainment. Audiobooks are better because I can multi-task. And most everything could be considered "philosophical knowledge", so it doesn't filter stuff.
Of course, the rule doesn't apply to HackerNews ;)
E.g., if you only try to learn things once you know you need them, you miss out on things you didn't know you could know.
That's a BIG loophole. He could have stopped after "If it doesn’t answer a specific question you’re currently asking".

(joke aside: will read it later, just couldn't stand making the silly comment. sry.)
My reaction is the same as yours.
