Hope is a muscle, a practice, a choice that actually propels new realities into being. And it's a muscle we can strengthen. It is not the same as idealism or optimism. This kind of hope has nothing to do with wishful thinking. Hope as I've seen it lived is at once fierce and persistently joyful. I've come to understand this quality of hope as an essential foundation and power for the generative story, the generative landscape, that is emerging out of all of the rupture this moment in the life of the world has laid bare.
