Master of Your Domain
Master of Your Domain
Build your own independent business as a knowledge worker with my complete guide to success.
Who is this book for?
Engineers, developers, consultants, and technical professionals who want more control over their career, income, and future.
What’s different about it?
Master of Your Domain isn’t like any business book you’ve read before. It’s not about how to start an LLC or format an invoice, though there’s plenty of practical advice in these pages. It’s really about training yourself in the skills you need to be able to direct your own career.
Many engineers dream of working for themselves, but the path isn’t obvious. How do you find clients? How much should you charge? How do you market your work without feeling like a salesperson? Where does money come from when you’re not employed by a company?
This book is a complete manual for the self-driving independent engineer. It covers everything you need to know: finding customers, pricing your work, creating products, building a sustainable business around your expertise, and creating the freedom to choose your own direction.
If you’re tired of waiting for other people to notice and reward what you’re doing, and give you the work you really want to do, stop waiting, and start reading. This book will help you become the kind of person who doesn’t need permission.
What will I learn?
The book will guide you through:
- Independence: understand your options and prepare for a self-directed career.
- Business: learn the secrets of pricing, clients, contracts, and getting paid.
- Consulting: turn your expertise into solutions that people value.
- Marketing: build an audience, reputation, and opportunities.
- Products: create scalable income through books, courses, and other knowledge products.
- Mastery: develop the skills, confidence, and reputation that make long-term independence possible.
And when you’re ready, you can take the next step by learning with me in person, through my Mastery mentoring.

“It's like John’s reading my mind.”
I had to buy this one, and I'm already enjoying it (and already making some good plans).
Jakub Jarosz, Author, 50 Go Testing Mistakes
“Inspired me to finally take the leap!”
Thanks to John’s book I’ve now launched my own independent business. I have since written and published my own book, 50 Go Testing Mistakes, and I'm currently working on new projects while applying John's many technical and practical business tips on marketing and promotion. If you pair this book with his other bestsellers, Monk Mode and Code For Your Life, you'll be well on your way to success too.
