The tycoons of social media have to stop pretending that they’re friendly nerd gods building a better world and admit they’re just tobacco farmers in… - Cal Newport

You have a finite amount of willpower that becomes depleted as you use it.

You cannot expect an app dreamed up in a dorm room, or among the Ping-Pong tables of a Silicon Valley incubator, to successfully replace the types of rich interactions to which we’ve painstakingly adapted over millennia. Our sociality is simply too complex to be outsourced to a social network or reduced to instant messages and emojis.

Another benefit of a sender filter is that it resets expectations. The most crucial line in my description is the following: “I’ll only respond to those proposals that are a good match for my schedule and interests.” This seems minor, but it makes a substantial difference in how my correspondents think about their messages to me. The default social convention surrounding e-mail is that unless you’re famous, if someone sends you something, you owe him or her a response. For most, therefore, an inbox full of messages generates a major sense of obligation. By instead resetting your correspondents’ expectations to the reality that you’ll probably not respond, the experience is transformed. The inbox is now a collection of opportunities that you can glance at when you have the free time — seeking out those that make sense for you to engage. But the pile of unread messages no longer generates a sense of obligation. You could, if you wanted to, ignore them all, and nothing bad would happen. Psychologically, this can be freeing.
