If like me you're still scratching your head as to why social media platforms are such a cesspool of trolls, weirdos and a seemingly endless parade of conspiracy theorists, you have to read this evidence-based analysis by Mark Manson.

Change your habits and your life will seem much more normal. I've been largely off of traditional social platforms for over 1.5 years and my life is noticeably better for it. The cure? Talking to people in real life. It's still as fun as ever.
