A common theme across employers is how to build a culture of learning. It's a phrase used so commonly that Google produces over a billion results when you search for it, turning up everything from scholarly treatises to "6 Ways to Build" clickbait-style blog articles on the subject. There are, in fact, many excellent pieces on the topic, which begs the question: why another? Why this book? I've read dozens, if not hundreds, of those pieces, and found many of them to be practical, actionable, and in most cases fairly concise. But I think too many of them focus exclusively on why you'd want a culture of learning, or precisely how they recommend you build one. Few attempt to concisely tackle the underlying question, though: what, exactly, is a culture of learning? I feel that understanding the answer to that question actually unlocks the how and why for you. Understanding that answer is what really "changes your brain," in a way that makes all the other answers obvious. Understanding that big, underlying answer also helps you really grasp the full scope of what a culture of learning is, and can be, to an organization. It highlights the real breadth and depth of the topic, and shows you how it can-and should-pervade everything your organization does. That's what this book is about.
