10KHP: How to Sell Air

About 70% filler, 20% self-promotion, and maybe 10% of something that actually makes sense. And it’s not cheap, either.
10KHP is a pretty solid example of how to turn a $25k ad budget into over $100k in profit - basically out of thin air.

I worked on the project as one of the contributors - through the intermediary Mark Diaz - and, as it often happens, I never got paid. The only “reward” was a digital copy of the book. Before this project, I’d never heard of Yu-kai Chou, and once I did, I couldn’t help but wonder how “life gamification” got marketed as something revolutionary. Having spent 20+ years in the game and film industry (RPGs, MMOs, you name it), I’ve seen those same mechanics in action - where they work for real, not as motivational slogans.

I saw the book being made from the inside - I lived and worked close to Diaz, saw how things were handled, and met Yu-kai. I could say a lot more, but I’ll keep it brief.

The book itself was partly written with ChatGPT (not mentioned anywhere, of course). Its actual purpose isn’t to teach gamification - it’s to softly push readers toward other Yu-kai products: Octalysis Prime, Framework, Group, etc. Nearly 500 pages long, but that’s more about justifying the price tag than providing real substance. The self-promotion starts right away:

“After my first book... selling over 100,000 copies worldwide...”
“Roughly 500,000 people a year learn about my work...”
“Created over thirty frameworks... impacting over 1.5 billion users.”

Sounds impressive, but good luck verifying that.
Yu-kai’s YouTube channel has under 5k subscribers; his most-viewed video (posted 12 years ago) has 33k views. Even his TED Talk sits at around 400k. The numbers simply don’t match the claims, and that “1.5 billion users” thing feels… too strange, to say the least.

Now about visuals and production quality... You can see the cost-cutting from page one. The cover was AI-generated, the illustrations were done by a freelancer in a very simple, amateur style, and the Octalysis Prime site looks about the same: non-professional and cheap.

Originally, the internal goal for Kickstarter was around $1 million, but it got lowered to $15k later. Still, over $25k went into ads. Mark Diaz got paid roughly $1,500 a month; I got $0. No contracts, and some of my work ended up being reused commercially without my consent.

When I left after ongoing pressure from Mark, he canceled my physical copy delivery and kept another book I’d personally bought (Framed Environment Design). Yu-kai never responded to my messages about it.

At first, Mark even posted online as if he - not Yu-kai - was the main author behind the book. Later, when 10KHP briefly appeared as “#1 Bestseller” in a small Amazon category, both authors began using that label in marketing materials. As of October 10, 2025, the book is not listed in any current Amazon bestseller rankings. The claim appears to refer to a short-lived category spike rather than sustained sales performance, which makes the “#1 Bestseller” badge misleading to potential buyers.

And yes, the book is literally inflated. The text uses a big serif font (around 13-14 pt instead of the usual 11-12), wide line spacing, and huge margins. There’s lots of blank space between sections, quotes, and headers, meaning each page holds only about 250-300 words instead of the usual 400-500. So roughly a third of the book’s “thickness” is just empty space and large print. It looks hefty, sure, but the actual amount of text equals maybe 200-230 normal pages.

Next... Let's talk about pricing and content. Prices vary: the digital version started at $9 on Kickstarter, about $3 on Amazon, and the full-color hardcover edition went for $169.
What do readers actually get? Regular time management dressed up as a “gamified system.” Tasks are “missions,” goals are “quests,” and a planner becomes your “character progression.”

If you’re new to productivity or just like RPG aesthetics, it might seem fun. But if you already know how to plan and manage your time, there’s nothing new here.

My recommendations:

Cut the book down to twenty pages, remove the constant self-promotion, polish the visuals, and, most importantly, treat contributors fairly and transparently.

And conclusion:

10KHP isn’t really a method - it’s packaging. A smartly marketed product built on presentation and hype rather than genuine innovation. A great example of how old ideas and strong PR can be sold as something “groundbreaking.”

This review is based on my personal experience working on the project and knowing the people behind it. I’m not bitter, just being honest, so future readers can make a fully informed choice based on reality, not advertising.
