      It is for a reason. Same here in middle eastern europe if you want to claim social assistance even if its literally only 56 Euro/ month you have to jump through many hoops and get through immense paper work. On the other hand, if you need to pay a fine or a social security fee, it's oddly easy and convineint. There is a serious effort to make giving up your money as frictionless as possible while recieving money as complicated and cumbersome as it can be made.

      Ugh, from what I can interpret, it's this:
      1. Look at the friction in a process/system: Does it serve a purpose? Or does it need to be fixed?
      2. If it needs to be fixed, ask yourself:
      A) do you know what you're doing (ie. How good can you estimatethe expected outcome)?
      B) is the decision reversible?
      Honestly, not really sure if this is the hack, but it's the take-home message for me. The editor and interviewer framed his thesis poorly.

    So, friction is an "obstacles that make it slower, harder, and more frustrating for customers, employees, and senior leaders to do something." It could be constructive or destructive. And a friction fixer should ask which one is which by asking 2 questions?
    Edit:
    * "Do I know what I'm doing?" This gets at the heart of constructive friction. If you're struggling because you're learning something new, stretching your abilities, or tackling a complex problem, that's often good friction. It means you're pushing boundaries and growing. If the answer is "no", it might be a sign that this friction is leading to valuable learning and improvement.
    * "Is it reversible?" This helps identify destructive friction. If the obstacle is causing permanent damage, creating insurmountable barriers, or leading to irreversible negative consequences, that's bad friction. Think of things like burning bridges with clients, creating hostile work environments, or making decisions that can't be undone. If the answer is "no", it's a red flag that this friction needs to be addressed immediately.
    Thanks Gemini for clarifying that for me😅

      Wait, that's wrong though? If an obstactle is leading to irreversible negative consequences, that's not bad friction? You WANT things that lead to irreversible negative outcomes to be hard - similarly if the answer to "is it reversible?" is no, that's not a sign that you need to address the friction "immediately", it's a sign that you should tread carefully and friction might be a GOOD thing. If the answer is "yes", THEN you should take a look at whether there's unnecessary friction.

    Here’s a paradox: If the guy had encountered more friction toward spreading this idea, he might have realized it was dumb and wouldn’t have said it. Ironically, that would prove his point! But the real problem isn’t that people make bad decisions due to a lack of friction. It’s that they’re bad at communicating clearly. Friction just makes them frustrated, rushing through things to ‘get it over with,’ leading to worse decisions. The solution is better communication, not more bureaucracy/friction.

    When I had Project Mgrs working under me, I taught them how to make it easy to get people to respond to your requests - everything you need to know (including reference links only if absolutely necessary) in ONE communication.) When teaching a skill, like doing a Project Mgmt plan, shoe them what good looks like (an almost perfect plan for a complex tech project) and ask them to tell you (after a few hours) what's good about it. Make it as easy as possible to do exactly what you want, folks - it's not rocket science (although it could be). Once you get a reputation for doing this, your future time will be conserved and people will respond almost immediately with any questions.

    Honestly just read Aristotle's Ethics Book 6 on the concept of Phronesis. Aristotle describes it WAY better.
    Essentially, it is an intellectual virtue focused on doing the right thing in the right way at the right time. It is making sure your means and your ends are ethical and aligned. Its about finding your telos, your goal, and using deliberative calculations to get there. Its about finding the golden mean (the perfect balance) in all situations eg being courageous is the perfect balance between recklessness and cowardness.
    What he (the guy in the video) is saying is basically knowing how to act depending on the situation and more importantly how how much thought to put into the decision, and thinkong about the community at large. Its just that Aristotle breaks it down better.

    Decisions are always more competent and risk-averse if you run them through these checks:
    1) Do I know what I’m doing?
    - if you don’t have full comprehension of the subject, don’t be hasty to make the decision. Do your homework.
    2) Is the decision reversible?
    - if yes, do it and see what happens. If no, slow all the way down and go back to educating yourself via step one

    What friction tries to do is it tries to slap you awake by putting the beauty of infinite creation a little piece of it up on display for you on a pedestal so you can look at it and say oh yeah. Of course. Look there it is. It's so beautiful. It's so amazing and then that opens your eyes a little bit and you can say oh yeah look that thing's beautiful too and that's beautiful and that's beautiful and that person's beautiful and I'm beautiful. Oh my god it's all so beautiful and then that takes you to a whole new level as a human being and then you can delight in reality and you can enjoy everything as one giant work of art.

    His comment about not knowing (and not really caring so much) whether he'll get a return on his investment in a company he believes in made me wonder if we could restructure investments ... imagine if every person had a certain budget per year that they would get a fixed return on by the government if it was invested (maybe just in research, maybe all companies, maybe have a higher return for non-profits and medical/environmental science ... ) but they would NOT get a return based on how profitable the business is. That would lead to people actually giving money to things that would benefit society, I think.

    He has a friendly personality, but in today’s fast-paced world, you need to make quick decisions; otherwise, you might miss opportunities that others will take. He also seems to miss an important point: trusting your team and surrounding yourself with talented people is key. It’s important to keep learning before making any big decisions.
    If you sit back and wait too long, you could risk losing your job because of missed chances. When he mentioned personally investing $25,000, it didn’t quite connect with the video’s headline.

      Also consider, if DJT becomes the president then JDV is capable of creating a coup to oust DJT and become president himself which is his ultimate goal. As he said previously he's not a fan of DJT or words to that effect, so he is playing the political game to maneuver himself into a position to seize power for himself. Beware, these people, DJT & JDV and all their sycophants, are sinister. Don't rationalize for a minute what MAGA, from the leaders (and sycophants) down to the foot soldiers, won't do if they seize power. The blueprint, Project 2025, clearly spells out the future that they will implement. Please don't be complacent, confirm you're registered then vote.

    Absolute joker. Shares nothing but common sense! I agree with the comment below, a complete waste of time.

    This had a thumbnail of "the universal hack" as a skeleton key. Overpromised, under-delivered, effectively clickbait. Add more friction to your thumbnail & hook creation process, please. Like the DMV guy, respect our time. I don't often downvote, but I wanted to share why.

    And now that we know Elizabeth Holmes went to prison becos she's a fraud, it makes his example a very bad one... fortunately I didn't need this video to tell me how to make smarter investment. That friction theory not a bad idea and concept but I prefer the one that says "The obstacle is the way". And like everything in life, you'd better know what you are doing or you can hurt yourself, die or hurt other people and get broke.
