Remember when people had the choice to not watch the news because it was negative. Now, social media not only makes you watch the news by filling your feed with it all day everyday, but also shows you stuff worse than you would ever of seen on the actual news.

Now 20 years on it's developed in such a way that it has significantly disconnected real life connections. If you spent the majority of your day, everyday for the next 6 months learning to play the guitar, you'd be very good at playing the guitar in 6 months. If you spend the majority of your day, everyday over a long period of time on your phone, consuming negative content then chances are, soon enough, you will be extremely good at viewing everything from a negative perspective. Food for thought.
