“That third idea, that we will never have to be alone, is central to changing our psyches. It’s shaping a new way of being. The best way to describe it is ‘I share, therefore, I am.’ … We slip into thinking that always being connected is going to make us feel less alone. But we are at risk, because the opposite is true. If we are not able to be alone, then we are only going to know how to be lonely.”
