    I have managed to completely give up social media, I can’t even remember the last I got on Facebook, Instagram,and Snapchat. I feel great and I’m not even interested in going back but I still have one big addiction and that is YouTube. It’s almost impossible for me to quit this
  • @Jhamuraa
    Me: mindlessly scrolling on youtube Youtube: lets make him realise
  • @1gomes307
    When you're using your phone to tell you why using your phone is bad.
  • @parn2160
    I once read something amazing in a book. "Overstimulation is inversely proportional to perception." And this makes so much sense. The more you deprive your senses of external stimulus like phones, the more perceptive you become. Your ability to think and imagine, to create, it soars back high and suddenly you're not crippled by the need for stimuli. Overstimulation is also the concept used in arcades, casinos, etc. to make people spend greater amounts for some 'positive' stimulus.
  • @Frey_64
    its not always "social interaction" its also just plain boredom, we so used to get entertained by our phones that we get bored so quickly and need that stimulus again
  • The benefits of reducing mobile usage: 1. Cognitive improvement 2. Increased attention span 3. Inc sleep quality 4. Better relationships 5. Dec anxiety,depression
  • @ayoaleja
    I think it also depends what your current environment is. I recently went on a 4 day trek in the remote rainforests of Colombia where i didn't use my phone and I didn't miss it all. I was very in the moment, somewhere new, somewhere amazing. I actually got anxiety when I got back to civilization and all my notifications came back. This would be much harder to achieve in the big city where I live in for sure.
  • Scrolling your Phones really is the same as changing channels on the TV, you get to a point you are like a zombie and are not really looking at anything
  • @PandaTheGreen
    Reduction is the key here. I've been taking slow steps to distance myself from my phone the last few months. Think of disabling notifications, only replying a couple times a day, leaving it faced down at my desk, ... All these things are very small changes, but I'm sure even those have benefits over time
  • @chairmanm7686
    Social media and apps that enables the mindless scrolling has allowed my procrastination to get out of hand and recently I’ve had this gut feeling that I need to change it since it has made me fall behind on responsibilities and things that I do really value, long term. This video made it clear and gave me that last push to make some well needed lifestyle changes! Does anybody else identify with the issues described above? Would be nice knowing I’m not alone. Let’s dive headfirst in to the withdrawals!!
  • i've never used tiktok, and wached only long videos on youtube. Im really happy about that.
  • @StratosAsa
    Great video!! 3 days no smartphone and i feel soooo free and more calm
  • @CarlsAnne
    Working in a medical lab has its perks. We have to assume everything is contaminated so no cell phones are allowed. I only check it when I'm at break, and this really allows me to focus on my work and be truly present in the moment.
  • @niya3550
    i switched to a flip phone 3 weeks ago and i've experienced all these things, notably decreased anxiety and depression which I've struggled with for a decade, and increased attention span (I have ADHD). one sort of negative thing i've experienced is how few of my "friends" interact with me now that i don't use social media and it's easier to call than text (though many of them wouldn't know because these people don't text me either!). It feels like a loss because I have fewer social interactions, but the quality of my social interactions has increased a lot. I don't want to interact with people who won't put in the slightest effort to talk to me, and without my head in my phone, i've talked to interesting strangers out in the world (i was previously so anxious i never thought i could do this but it's awesome).
  • @quchi7232
    Deleted all my social media except this, now I'm addicted to listening documentaries or infotainment in general.
  • Been trying to explain to my family members who text me TikToks all day why they should stop. Thank you so much for this 😂
  • @Flowtups
    Just wondering if the internet were to be shut down just for 1 day all around the world. What exactly would happen?
  • Quitting phone these days for a med school student like me is flat out impossible to be honest. So much communication is there with my classmates, with professors, so many study materials, etc. I think it's not the phone that should be quit, it's the usage to be culled down. Easiest way to do this is to delete all social media like tikotok, Instagram. Too bad I am addicted to educational YouTube videos ahaha
  • Social media makes me feel that iam not alone, while the real world makes me feel lonely.
  • I’ve gone 4 months with out social and let me tell y’all it does wonders!
