This is a great book. Although it is written for activists, I think there are great lessons and tools for everyone.

The book uses a systems thinking, which "suggests problems are multiple, interrelated, and complex, solutions are unknowable in advance and likely to emerge through trial and error, and at least some villains are likely to also be indispensable allies in bringing about change."

It shows that change happens on several levels and can begin in multiple ways. That's why we need to understand the intrinsic characteristics of each system, its feedback and dinamics within itself and with the rest of the systems.

One must accept that "you cannot understand and plan everything in advance. If each situation is different, so must be the response."

It is about thinking and understanding complex adaptive systems in order to change the status quo.

Great reading.
