There was a lot of conversation at the time around a leaderless movement. But I know at least in the activist scene in New York, what we talked about was building leader-full movements, about the idea that we don't want to step away from power, but instead, as people with a vision for the future of America, we want to step into power.

One of the biggest lessons of the Occupy movement was that you can't only have a demonstration. Demonstrations are great. Demonstrations are important to bring attention to certain critical issues. But if you lack mobilization and organization and a political strategy, then you're just basically engaging in a performative act. You're indulging in a performance. You aren't really changing the course of history.
