Most teachers have to lead their own practice. They have to dig down deep every day to forward their efforts in ways that matter. They also have to continually advocate for what they believe to be right and good for children.
Of course, I'd like to see education organizations morph to organizations with greater distributive leadership and teamwork as I think that would create more inspiring places to teach and learn. That happens, in part, now, but I think greater dedication to that will continue to improve what we can do and how we do it.
