How to Change: The Science of Getting from Where You Are to Where You Want to Be

Most self-help books treat willpower as the solution to every problem. Katy Milkman, a behavioral scientist at Wharton, argues that's exactly backwards. The real question isn't how to try harder — it's how to diagnose the specific obstacle between you and the change you're after, then match your strategy to that obstacle. Whether it's procrastination, forgetfulness, a lack of confidence, or simply that good habits feel like a grind, Milkman shows that the same intervention won't work for everyone, and that applying the wrong tool can make things worse. The stakes are personal: this is a book about finally closing the gap between who you are and who you keep intending to become.

What sets Milkman's approach apart is the rigor behind it. She draws on decades of field experiments — not just lab studies — conducted with real people trying to exercise more, save money, and stick to plans. The writing is crisp and unusually honest about where the research is still unsettled. Milkman structures each chapter around a distinct psychological barrier, making the book easy to navigate toward whatever's actually blocking you. It reads less like a prescription and more like a thinking partner who has done the hard work of reading the science so you don't have to.
