More About This Book

I wrote this book just for women. My coaching practice is limited to women, and they often express concern about lacking confidence. Some clients say they suffer from the Impostor Syndrome.  A lack of confidence hurts women at work, at home and in virtually every aspect of their lives. 

But a confidence deficit isn’t permanent. Just as you can strengthen a muscle, you can strengthen your confidence. I’ve seen my clients do it, and their stories fill the pages of this book. I draw on proven techniques from biology, psychology, and neuroscience to create an easy-to-understand guide for making confidence part of your life every day. 


“[B]oth inspirational and practical, McGuinness provides a playbook of the techniques she employed to rebuild her lost confidence.… McGuinness is unfailingly positive, dishing out encouragement every chance she gets, as she draws on her experience and relates it to other women’s challenges. The author backs up her insightful strategies with notes that reference a multitude of articles and books, which makes for an even stronger presentation. A compassionate and energizing guide full of confidence-building ideas.”

Kirkus Magazine

Pat Heim, author, Hardball for Women and In the Company of Women 

Crystal clear, compelling, refreshing. Kate McGuinness is a trustworthy guide through the complexities of recovering and rejoicing in our own competencies. Anchored in solid cutting-edge science and clinical expertise, McGuinness shows the reader, step-by-step, how confidence lost can be more than found; it can be claimed and celebrated as one’s own being.  Terrific!”

 Linda Graham, MFT, author of Resilience: Powerful Practices for Bouncing Back from Disappointment, Difficulty, and Even Disaster

This is a guidebook to conquer that self-doubt that every woman has experienced at some point in her life—a lack of confidence.

 Desiree Moore, author, Thrive

“Building on a solid foundation of research and life experience, Kate McGuinness provides a heartful account, interwoven with poignant client anecdotes, of how confidence fades and how to regain it.  Her tone is inspiring and her prose is highly readable, but more importantly, her advice is straightforward and practical.  Drawing on core concepts of mindfulness and wellness, Confidence Lost, Confidence Found delivers a wealth of strategies to help readers enhance communication skills, identify insidious automatic thoughts that hold us back, cultivate positive states of mind, bolster gratitude and nurture healthy, loving relationships.”

Rebecca Gladding, M.D., co-author, You Are Not Your Brain

“Lost confidence becomes an inner narrative that holds back so many women. From on the job performance to job interviews, networking, public speaking and more, Kate McGuinness offers women research-backed tools to find their confidence and perform more effectively than ever before. Kate’s book is like having a mentor available to you 24/7.”

Andrea S. Kramer, coauthor of It’s Not You, It’s the Workplace: Women’s Conflict at Work

Kate McGuinness’ book is such an inspiration for so many people particularly women who have struggled and continue to struggle with accomplishing the impossible, PERFECTIONISM.  McGuinness’ words wouldn’t not have such power, truth, and relatability had she not gone through her own struggles in life. Furthermore, Ms. McGuinness effectively conveys the message that when faced with adversity accompanied by shame or self-doubt, there is a way to recreate one’s narrative with tools that she generously shares in her book. Must read!

Kate’s Journey to Reclaim Her Confidence

Despite achieving career success and accumulating wealth, I lost both—not once, but twice. In truth, I didn’t “lose” them. They were taken from me. But my story isn’t about loss—it’s about what I’ve gained as I’ve reclaimed my confidence.

The double hit sent me into a place where I was overshadowed by fear. To find my way out, I had to become mindful so I could discover my authentic self and abandon self-defeating behaviors that undercut my confidence. It took time, but I’m here now to help other women.
