There are so many books that have given me an unfair advantage. I could easily list a dozen but the question asks for one.
I'd say we live in an age of overinformation. There are books that give you an edge, like Never Split the Difference, and then everyone reads it, and then everyone reads the summary of it, then everyone criticizes the summary (which the original book itself has addressed), then everyone reads the criticism and concludes that the book is bad.
You can ask people what a startup is, or what a MVP is, or TDD, and I assure you most would not have the original definitions or purposes from the books. A lot of people think TDD is 100% test coverage or that a startup is a business, but these are all wrong by definition.
