I've bought the book and read until the Delegation chapter.
Up until now I find that the topics are interesting and the writing is very direct and unpretentious which I appreciate.
I also like the approach you took of wrapping it in a story, I think it makes the topic a lot less dry.
At the same time I feel that it doesn't go into the detail I would like.
For instance I feel that the “How to Measure Your Output as a Manager” is a bit hand waved by using Andy Grove's equation. This is a topic I struggle with because I sometimes feel that I don't produce anything as a manager and that is frustrating.
Nonetheless, the chapters I've read are fine as a starting point and appreciate that you suggest additional literature to deepen the topics.
Overall I'm positive about the book, would buy again :)
