If social media or anything else is causing more harm than good, I say stop doing it. Even if quitting is hard. Don’t invest more into something than you get out of it, is something I firmly support. I have essentially stopped using Facebook because of that, but I recognize that for many people, quitting Facebook would have a negative impact on their life because they get more out of it than they put into it.
Still, I can’t get behind the whole “you should quit becusss x, y, z” thing. Like, as much as I like to rip on social media (especially Twitter), my life has been changed and enhanced and is demonstrably and unquestionably better because of social media. I realize that isn’t the case for everyone, but for me, it is. I use what has a positive impact on my life and don’t use what doesn’t, the same as with anything else.
