I really loved the perspective on building excellent products that this book provided (and a lot of what Seirra wrote about matches with what we see at TSG). I took a handful of notes that I'll be revisiting as I work on StoryGraph. However, at times, the format felt a little off and it felt like the book went on a bit of a tangent at times — on expertise and mastery — and didn't always effectively tie it back to actionable insights for your product. On the whole, a great, quick read and I'd recommend it to any product person!
