Writing a book exposed gaps in my expertise I didn't know existed
Corey Quinn
Founder, Deep Specialization™
I thought I understood agency specialization completely until I wrote "Anyone, Not Everyone." Here's how putting my ideas on paper transformed my own thinking...

Nothing forces clarity like writing.
What you think you understand will get tested. Hard.
I thought I understood specialization inside and out, but writing ‘Anyone, Not Everyone’ forced me to refine my thinking even more.
It made me sharper. More focused. Less tolerant of fluff.
The biggest surprise is how I now approach my own work.
When you’re forced to explain something clearly, you see the gaps in your own logic. It made me rethink how agencies position themselves, how they communicate value, and what truly makes a business stand out.
Writing a book was about deepening my own understanding.
If you think you understand your expertise, try writing it down... and watch how much you grow.

Frequently Asked Questions
Why did writing a book change an understanding that already felt solid?
Because writing forces clarity in a way that just knowing something doesn't. What feels understood in your head gets tested hard once you try to explain it clearly on paper, and gaps in logic become impossible to ignore.
What actually changed after writing Anyone, Not Everyone?
Thinking got sharper, more focused, and less tolerant of fluff, both in how specialization is understood and in how the work itself gets approached day to day.
Did writing the book mainly serve readers or the author?
Both, but the deeper value was personal. Writing it was as much about deepening understanding of the topic as it was about explaining it to anyone else.
What did the writing process reveal about agency positioning?
It led to rethinking how agencies position themselves, how they communicate value, and what actually makes a business stand out, ideas that only got sharper by being forced into clear language.
Is there a way to access the book without reading it cover to cover?
Yes, the audiobook is available for download, and the book has now been out for a year with thousands of readers.
