Short and easy read. I wish it was useful.

From one point of view, it introduces powerful tools for system thinking (stocks, feedback loops, and a couple more) and provides many examples. I like how the author defines all the terms she uses. I like how the book is structured. There're hundreds of well-put sentences.

From another point of view, it could be much shorter. I wish there were better examples, but, I guess, the author wishes it too. I could almost feel her frustration when she tries to find an example that is correct, useful in real life, and is not an oversimplification of some system.

Sometimes it goes straight into politics. I find it disgusting because political problems don't even need any special ways of thinking to be criticized.
