The Refactoring book completely changed the way I code.
In 2001 while searching for information on design patterns, I discovered the original wiki and stumbled onto Extreme Programming. This led me to a software development conference in 2002 called SD West. There I attended a session by Martin Fowler, and knew that I had to pick up his Refactoring book that day.
How could I resist a book that promised to teach me about “improving the design of existing code”?
Refactoring: Co-opted in the Workplace?
Many years later, I find the term “refactoring” being thrown around in the workplace, at company after company. Programmers and managers often talk about “refactoring,” when they mean “rewriting.” I’ve seen nightmares brought about by so-called “refactoring” that introduced so many defects, it compromised the product ship date.
Programmers talk about "refactoring," but they usually just mean "rewriting."
The Refactoring book, however, teaches a disciplined methodology of changing code in small steps, with automated verification of each step.
Of the books I have at work, I keep just a few within easy reach for looking things up. This is of those books. Each refactoring has a detailed recipe of its steps. Things usually go better when I open the book to follow those precise steps.
If my statement that it “completely changed the way I code” seems like hyperbole, another blogger states it even more strongly: “That moment changed my life.”

- Hamlet D'Arcy wrote a classic blog post about the current state of refactoring in most companies: “You're not refactoring; you're just changing s***.”
