Here's the best piece of advice I can offer. Delete your social media accounts immediately. Next, every morning, begin the day by reading a book, taking a walk, whatever. Just don't waste it reading the news about our dear leader's headfirst dive into authoritarian hell or your old friends transformation into an (anti) racist corporate guru. This will make your day 100x better.
Otherwise, if you work for a social media company, kill yourself. You are making the world a worse place.
Now get out there and do something honest and constructive. Together we can beat narcissism!
