I could have done without the first 20% of the book, because it was just a long version of "I hate nanowrimo but I like nanowrimo. But mostly I hate it." - And to be clear, this is not about the opinion itself, it's about why do I care about this, when I am reading this to learn to outline quickly, not how to write for nano specifically.

That said, I liked the question prompts and that there was an actual example. But there was nothing groundbreaking here, and if you need a bit more on structure, other books are better.
Also the 3 hour thing is debatable.
