I think this is true about more than just commutes. Aside from Instagram and this place, social media just makes me disgusted by my friends and the media. What's the point of something that worsens relationships, which are the only thing that matters? Maybe this election made me realize how angry and unfocused it all makes me feel, but either way I've blocked those sites with an extension.
I feel much calmer now, and I'm pretty sure I'm more productive. I also feel like I have more energy for things that matter, like going to the gym frequently. I think "the feed" of social media is exhausting and unending, and feels very unhealthy.
