I got an advance copy of Pat Flynn's book Will It Fly? back in early 2016, and I was so excited about it that I recorded a video review from my car on the way home from work. Plosives and all. That enthusiasm was warranted. Nearly a decade later, Will It Fly? remains one of the best books for entrepreneurs who need a framework for validating business ideas before investing serious time and money.
What the Book Is About
Will It Fly? is Pat Flynn's guide to testing whether a business idea is worth pursuing before you go all in. If you are like me, you have a new business idea every five minutes. The problem is not coming up with ideas. The problem is figuring out which ones are actually viable.
Pat structures the book around the metaphor of building a paper airplane and testing whether it will fly before building a real one. He walks you through a systematic process:
- Mission Design: Aligning your business idea with your personal values, goals, and lifestyle. This is the part most business books skip, and it is arguably the most important.
- Development Lab: Researching your market, understanding your target audience, and identifying whether real demand exists for your idea.
- Flight Plan: Mapping out how the business will actually work, including revenue models and competitive positioning.
- Flight Test: Validating with real people before spending real money. Pat gives you specific exercises and frameworks for getting honest feedback from potential customers.
Why It Still Works in 2026
Business validation is timeless. The tools and platforms change, but the fundamental question — will people actually pay for this? — never goes away. Here is what makes Will It Fly? hold up:
- It is practical, not theoretical. Every chapter has exercises you can actually do. This is not a book you read and put on the shelf. It is a workbook.
- The personal alignment section is rare and valuable. Most business books jump straight to market analysis. Pat forces you to ask whether this business idea actually fits the life you want to live. That filter alone will save you years of pursuing the wrong thing.
- The validation framework scales. Whether you are testing a blog topic, a course idea, a SaaS product, or a physical product, the core process of finding your audience, asking the right questions, and testing with a minimum viable offer still applies.
What to Keep in Mind
A few things have evolved since the book was published:
- Market research tools are more powerful. Pat references some tools and techniques that have been superseded by better options. Use SparkToro for audience research, Reddit and online communities for qualitative validation, and pre-sale landing pages for quantitative testing.
- AI can accelerate validation. You can now use AI tools to quickly analyze competitors, generate survey questions, summarize customer feedback, and build MVP landing pages in hours instead of weeks.
- Pat Flynn is still active and still credible. He continues to run Smart Passive Income, has expanded into YouTube and community-based businesses, and practices what he preaches. That matters for the credibility of the advice.
Who Should Read This Book
If you have a business idea and you are not sure whether to pursue it, read this book before you spend any money. If you are a serial idea person who starts things and abandons them, read this book. If you are building an online business on the side and your time is limited, read this book so you spend that limited time on the right idea.
You can find Will It Fly? on Amazon or wherever you buy books. It is a short, focused read that will pay for itself many times over by helping you avoid bad ideas and commit to good ones.
Highly recommended. That has not changed since my first impression in 2016.
