Amy Morin's 13 Things Mentally Strong People Don't Do is the essential playbook for developing the resilience needed to not just survive, but thrive. As a seasoned psychotherapist, Morin moves beyond platitudes to offer a counterintuitive and actionable framework. Instead of adding more to your to-do list, she identifies the 13 destructive habits that secretly sabotage your progress—from wasting energy on things you can't control to resenting other people's success and fearing calculated risks. Each chapter breaks down a specific habit, providing clear examples and practical strategies to eliminate it from your life and leadership style. This isn't about suppressing emotion; it's about regulating it to make smarter decisions under pressure. For the entrepreneur, mastering these principles means building the unshakeable core needed to navigate crises, inspire teams, and maintain focus on your vision. If you're ready to trade self-doubt for strength and build the mental muscle required for long-term success, this book is your indispensable guide.
