From Teenage Poet to Publishing Powerhouse
Keith Wheeler was born in Danbury, Connecticut, and at age 9 moved to Port Orange, Florida, where he would eventually marry his high school sweetheart, Suzette. His publishing journey began remarkably early. Wheeler’s first published work appeared while he was still a freshman in high school, a poem featured in the same poetry book as his maternal grandmother, Ethel Morsey.
Today, Wheeler lives in southwest Missouri with his wife and their four children, and his publishing philosophy remains refreshingly inclusive and empowering. As he often says, “Nothing makes me happier than to see a child smile while reading a book!”
Through his YouTube channel Keith Wheeler Books and his 30-day coaching program, many of Wheeler’s students have achieved Amazon bestseller status. His expertise spans multiple genres and niches, from softball journals to children’s read-along picture books, but he’s become particularly renowned for his mastery of puzzle books and activity books.
The Keith Wheeler Book Catalog: A Diverse Portfolio
Keith Wheeler’s bibliography demonstrates his versatility as a publisher and his keen understanding of multiple profitable niches within Amazon KDP.
Puzzle and Activity Books
Wheeler’s signature works focus on solving a specific problem: keeping children entertained during travel and downtime. His puzzle book collections include:
Travel Softball Activity Books: These books address the universal parent complaint of “Are we there yet?” during long tournament trips. The books contain over 100 pages of softball-themed entertainment games including Hangman, Mazes, Word Scramble, Sudoku, and Word Match. Wheeler created multiple versions targeting different age groups, demonstrating his understanding of market segmentation.
I Love Softball Activity Book Series: Available in both full-size and pocket editions, these books combine Wheeler’s personal connection to the sport through his daughter with proven puzzle formats that keep young athletes engaged between games.
The genius of these books lies in their niche specificity. Rather than creating generic puzzle books, Wheeler identified an underserved market: softball families spending hours traveling to tournaments. This targeted approach reduces competition while addressing a genuine need.
Educational and Coaching Resources
Make Money Self-Publishing Puzzle Books: A Step-by-Step Guide to Starting Your Low Content Journey: This is Wheeler’s flagship teaching book, where he distills his years of experience into actionable guidance. The book covers why puzzle books trump other content types, niche selection strategies, working with images, creating captivating puzzle books, crafting covers, and launching successfully with strategic ads.
The book represents Wheeler’s teaching philosophy in action. Rather than keeping his success secrets to himself, he openly shares the exact strategies that built his publishing empire.
Ultimate Softball Journal Series
Inspired by his daughter who lives and breathes softball, Wheeler created a series of four softball-themed journals: My Ultimate Softball Journal (for players), My Ultimate Mom’s Journal, My Ultimate Dad’s Journal, and My Ultimate Coach’s Journal.
Wheeler recognized that generic notebooks with softball pictures weren’t meeting the needs of players and families who wanted to document their softball memories. His journals provide structured prompts and sections specifically designed for the softball experience, from tracking stats to recording favorite moments at the ballpark.
Children’s Picture Books
While Wheeler is best known for puzzle books, he also publishes children’s picture books and read-along stories. This diversification protects his income stream and allows him to serve different market segments within the children’s book category.
Why Keith Wheeler’s Content Is Genuinely Helpful
Wheeler’s educational content stands out in the crowded self-publishing coaching space for several compelling reasons:
1. Active Practitioner, Not Just Teacher
Wheeler has published over 250 books in a variety of genres and niches. He’s not teaching theory from the sidelines; he’s actively publishing, testing strategies, and adapting to Amazon’s ever-changing algorithms. When he teaches a technique, it’s because he’s using it successfully right now in his own business.
2. Accessible Entry Point
Wheeler democratizes publishing by focusing on low content and puzzle books, which don’t require writing talent or expensive ghostwriters. According to KDP’s Terms of Service, even minors can make money self-publishing books, with a parent or guardian opening the account. Wheeler explicitly teaches strategies that work for teenagers, stay-at-home parents, college students, and retirees alike.
His message is clear: you don’t need to be a professional writer to build a successful publishing business. You need systems, market research, quality design, and consistency.
3. Niche-Specific Expertise
While many KDP coaches teach general principles, Wheeler specializes in puzzle books, giving his students a competitive advantage in this specific segment. He understands:
- Which puzzle types sell best in different niches
- How to research puzzle book demand
- Image sourcing and creation techniques specific to puzzles
- Pricing strategies for consumable content
- How competition matters differently for highly consumable books like puzzles
4. Complete Systems Approach
Wheeler’s teaching covers niche selection, brainstorming and researching, working with images, creating puzzle books, crafting covers that “practically leap off the screen,” launching successfully, strategic advertising, and marketing promotion. Students don’t just learn one piece of the puzzle; they get the complete roadmap from idea to income.
5. Proven Student Success
Many of Wheeler’s students have gone on to achieve their own Amazon bestseller status through his YouTube channel and 30-day coaching program. This track record of student results validates his teaching methods beyond his own personal success.
6. Transparent Philosophy
Wheeler openly shares his publishing philosophy: “EVERYONE from 7 to 107 has a book inside them waiting to come out”. This inclusive, encouraging approach makes publishing feel achievable rather than intimidating. He’s not gatekeeping knowledge; he’s actively trying to help others succeed.

Wheeler maintains an active presence through his website kwheelerbooks.com, YouTube channel, and email newsletter, providing free value alongside his paid courses. Students can start learning from him at no cost, building trust before investing in deeper training.
Keith Wheeler’s Unique Edge in Content Creation
Several distinctive factors set Wheeler apart in the self-publishing education space:
Personal Story and Relatability
Wheeler’s journey from publishing his first poem as a high school freshman to becoming an award-winning author with 250+ books creates an inspiring narrative. He’s not a Silicon Valley tech entrepreneur or trust fund kid; he’s a married father of four from Missouri who built his business through knowledge and persistence.
Focus on Quality Over Quantity
Wheeler emphasizes that “the most important elements in any book are quality interiors and quality covers,” warning against trying to throw together a bunch of no content books and hoping they sell. This quality-first approach helps his students build sustainable businesses rather than getting accounts terminated for poor quality.
Family-Inspired Content
Wheeler’s best-selling books emerged from personal experience with his softball-playing daughter. This authentic connection to his niche gives his books genuine utility rather than being purely cash grabs. He teaches others to find similar authentic connections in their chosen niches.
Simplified Teaching Style
Wheeler breaks down complex topics into digestible, actionable steps. His conversational tone and use of real examples make publishing feel achievable. He doesn’t overwhelm beginners with jargon or unnecessary complexity.
Specialization in Consumable Content
Many KDP educators focus on journals, planners, or coloring books. Wheeler carved out expertise in puzzle books, which have unique advantages:
- High consumability means customers need to buy new books regularly
- Less direct competition since they require more creation skill than blank journals
- Multiple puzzle types allow for product line expansion
- Works well for niche targeting (softball puzzles, travel puzzles, etc.)
Award Recognition
Wheeler won the 2020 Pinnacle Award for Children’s Educational Books and is an International #1 Best Selling author. These credentials provide social proof and credibility that enhance his teaching authority.
Strategic Course Offerings
Wheeler offers both a comprehensive coaching program priced at $1,500 and his more accessible Puzzle Book Domination course at $121, allowing students to choose the level of support they need. This tiered approach makes his expertise accessible to different budget levels.
The Amazon KDP Self-Publishing Opportunity: Statistics That Prove the Future Is Bright
Keith Wheeler’s decision to focus on Amazon KDP self-publishing and teach others to do the same is backed by remarkable industry statistics showing this field offers genuine opportunity for dedicated publishers.
Massive and Growing Platform
More than 1.4 million self-published books are released on Amazon annually, demonstrating both the platform’s accessibility and the sheer volume of content being created. While competition exists, this massive number also indicates enormous reader demand.
Amazon releases over 1.4 million self-published books through its Kindle Direct Publishing every year, and pays over $520 million in royalties annually to over 1 million authors who self-published through KDP. This means real money is flowing to real authors.
Market Dominance
Amazon continues to dominate the ebook space with a 68% market share. For self-publishers, this concentration is actually beneficial because it means focusing on one platform can reach the majority of the market.
When it comes to ebooks, Amazon is dominating the market by a wide margin, with the company’s market share in ebook sales standing at least 67%, climbing to 83% when Kindle Unlimited is included.
Amazon roughly accounts for over 50% of the physical book sales and around 68% of the ebook sales in the US. No other platform offers comparable reach for self-publishers.
Substantial Earning Potential
Self-published writers on Kindle make around $150 per month on the lower end to more than $20,000 per month on the higher end. While results vary based on niche, quality, and marketing, the potential for significant income exists.
Total royalties paid out on Amazon KDP were over $260 million in 2018, increasing to over $300 million in 2019, showing consistent year-over-year growth in author earnings.
With writers getting paid more than $575 million in 2023 through Amazon’s Kindle Unlimited Global Fund, it is evident that self-publishing continues to be a lucrative opportunity, and earnings on Kindle continue to increase year-by-year.
Favorable Royalty Structure
Amazon KDP offers up to 70% royalties on each ebook sale if you price your ebook between $2.99 and $9.99, and print books come with a fixed 60% royalty rate (though this was adjusted in 2025 for lower-priced books). These royalty rates far exceed traditional publishing, where authors typically receive 10-15% of net sales.
Continued Platform Growth
In the last five years, new titles on Kindle have increased by a whopping 264%. Rather than market saturation, this growth indicates expanding reader demand that’s growing faster than supply in many niches.
Starting June 10, 2025, royalties for paperbacks and hardcovers priced below regional price thresholds were reduced from 60% to 50%, but Amazon also reduced printing costs in 2025, which helps offset the royalty drop. While changes occur, Amazon continues investing in the platform.
Global Reach
As a Kindle author, you can select the territories you want to sell your book in with just the click of a button and can handpick the distributors you want to work with right from your Kindle dashboard. This global distribution would be impossible for individual authors without Amazon’s infrastructure.
Self-publishing authors have the option to publish their work in 40 languages, opening massive international markets to any publisher willing to invest in translation.
Low Barrier to Entry
Amazon makes it incredibly simple to self-publish a book: just create a KDP account, format and upload your book’s manuscript using the tools provided, and hit publish with no middleman, no hassles, and no cost. This accessibility democratizes publishing in unprecedented ways.
Amazon KDP has a simple, user-friendly interface with useful prompts, demonstration videos, forums, help centers, and FAQs, and you can publish your book in a matter of hours.
Strong Self-Publishing Market Share
Self-published books account for 31% of Amazon’s ebook sales, proving that readers don’t discriminate against self-published content when it’s high quality. Indie publishers compete on equal footing with traditional publishers.
90% of self-published authors utilize KDP and its print-on-demand services, making it the clear industry standard.
The Broader Publishing Industry Context
The overall publishing industry remains healthy and growing, providing a strong foundation for self-publishers:
In 2024, the U.S. publishing industry achieved a remarkable $32.5 billion in total revenue, representing a significant 4.1% increase from the previous year.
The book publishers market size has grown steadily in recent years, growing from $95.02 billion in 2024 to $97.71 billion in 2025 at a compound annual growth rate of 2.8%.
The book publishers market size is expected to see steady growth in the next few years, growing to $110.15 billion in 2029 at a compound annual growth rate of 3%.
Digital Format Growth
Online sales for books are projected to grow at a CAGR of 5.3% over the forecast period of 2025-2033, driven by increasing digital literacy, expanding e-commerce penetration, and the rising availability of region-specific content.
Print Resilience
Contrary to predictions of print’s demise, physical books remain popular. Amazon sold 308 million print books in 2025, indicating healthy 2.4% year-over-year growth, while major bookstore chains like Barnes & Noble saw print sales decline by 1.3%. Self-publishers benefit from this shift away from physical bookstores toward online print sales.
Niche Market Opportunities
The puzzle book niche Wheeler specializes in is part of the broader activity book market experiencing growth. In March 2025, HarperCollins India launched Booktopus, a new imprint for preschoolers and early readers featuring board books, puzzle books, touch-and-feel books, sticker books, and lift-the-flap books, indicating major publishers recognize the value of this category.
The Low Content and Puzzle Book Advantage
Wheeler’s focus on low content and puzzle books offers specific advantages that make this niche particularly attractive:
Lower Production Costs
Unlike full-length novels requiring ghostwriters or months of writing time, puzzle books can be created quickly using templates and software tools. This allows publishers to test multiple niches and scale successful products rapidly.
Repeat Purchase Behavior
Puzzles are consumable content. Once someone completes a puzzle book, they need to buy another one. This creates recurring revenue opportunities that journals or planners (typically one-time annual purchases) don’t offer.
Multiple Product Variations
A single puzzle concept can be adapted for different demographics: kids’ versions, adult versions, large print for seniors, travel sizes, themed collections, and difficulty levels. This allows rapid product line expansion.
Less Review Sensitivity
While quality still matters, puzzle books are less dependent on lengthy, detailed reviews than novels or self-help books. The concept is straightforward, and customers can assess fit through the preview pages.
Evergreen Content
Unlike trend-based books that lose relevance, puzzles remain evergreen. A well-designed Sudoku or word search book published today will still be relevant in five years.
The Future of Amazon KDP and Self-Publishing
All indicators suggest the self-publishing industry will continue growing, making Wheeler’s expertise increasingly valuable:
AI Integration
The introduction of generative AI in 2022 has rocked the writing world in every aspect, with more businesses, writers, and publishing companies utilizing AI to enhance their writing, build more efficient workflows, and get unstuck in their writing. Publishers who learn to ethically incorporate AI tools will have significant productivity advantages.
Continued Digital Growth
Self-publishing trends, subscription models, audiobooks and podcasts, sustainable printing practices, and diversity and inclusion initiatives are driving growth in the forecast period.
Global Expansion
The Asia-Pacific region is witnessing high growth in the market for book publishers owing to increasing literacy levels, internet penetration, and growing middle-class population. Self-publishers can tap these expanding markets without leaving home.
Educational Publishing Strength
The educational and academic book market remains a reliable revenue driver for publishers, with ongoing government and institutional demand. Activity and puzzle books that support learning benefit from this structural demand.
