Obligation.

We all — adults and children, writers and readers — have an obligation to daydream. We have an obligation to imagine. It is easy to pretend that nobody can change anything, that we are in a world in which society is huge and the individual is less than nothing: an atom in a wall, a grain of rice in a rice field. But the truth is, individuals change their world over and over, individuals make the future, and they do it by imagining that things can be different.

Just look around this room.  Everything you can see, including the walls, was, at some point, imagined. Someone decided it might be easier to sit on a chair than on the ground and imagined the chair. Someone had to imagine a way that I could talk to you in London right now without us all getting rained on. This room and the things in it, and all the other things in this building, in this city, exist because, over and over and over, people imagined things. They daydreamed, they pondered, they made things that didn’t quite work, they described things that didn’t yet exist to people who laughed at them.

And then, in time, they succeeded. Political movements, personal movements, all begin with people imagining another way of existing.
