After doing a Ctrl-F for "need" and not finding any distinction between needs and wants, I'm wondering if you understand what a human need is and if this book helps uncover actual needs versus things that aren't needs.
... and has also broken the extra guidelines that apply to Show HN threads (https://news.ycombinator.com/showhn.html).
Can you please follow the rules in the future? We want HN to be a place where people's work can be discussed respectfully and substantively. There's plenty of room for asking questions, offering critiques, and so on, but we don't want a putdown culture of trying to make others look like idiots. There's enough of that elsewhere on the internet.
To the OP, the book looks interesting and I've started reading it from the top. FWIW btw, it loads very quickly on my end.
