Grind vs. Groove is written for adults who have done everything "right" and are still exhausted by the way they're supposed to learn, work, and keep up. Drawing on thousands of hours with people facing high-stakes exams and demanding careers, it exposes why traditional grind-based methods overload the modern brain. Then it offers a different model—Groove—where you treat attention, time, and energy as assets to design around, not problems to push through. This book gives you language, tools, and examples to rebuild your performance on terms that are sustainable, effective, and genuinely your own.
