I'm going to apply the wise words of Paul Graham now:
"But while some amount of bullsh*t is inevitably forced on you, the bullsh*t that sneaks into your life by tricking you is no one's fault but your own. And yet the bullsh*t you choose may be harder to eliminate than the bullsh*t that's forced on you. Things that lure you into wasting your time on them have to be really good at tricking you. An example that will be familiar to a lot of people is arguing online. When someone contradicts you, they're in a sense attacking you. Sometimes pretty overtly. Your instinct when attacked is to defend yourself. But like a lot of instincts, this one wasn't designed for the world we now live in. Counterintuitive as it feels, it's better most of the time not to defend yourself. Otherwise these people are literally taking your life."
