An editor does not write the book. A consultant does not run the company. But what they both provide is the rigour of asking - what are you actually trying to do, and are you doing it? In this sense, the best editors and the best strategic consultants hold the client to the best version of themselves. The goal is never to make the book sound like the editor, or the brand sound like the consultant. It is to make each sound like the truest version of itself.
