I used to think that if I didn’t know the solution to the problem, I could figure one out. I now think some problems are so complex that there can never be a silver bullet.
I used to think we needed to create model schools that could then be replicated. I now think that it is so hard to sustain a model that each school needs to be invested in its own unique vision.
I used to think our goal should be to create systems of great schools. I now think great schools are so hard to create and maintain that our goal should be to create good and sustainable ones.
