From Doubt to Do: Navigating Your Path to Possibility is for anyone facing a significant transition who has doubts about what else is possible, no matter what stage of life they are in. Kat believes when Shift Happens, it’s time to Make Magic Happen. And that when we accept the invitation to make a shift, we open ourselves up to new possibilities.

In Part I, Kat shares stories of personal and professional transformation, inspirational quotes, and thought-provoking questions that will inspire you to have the courage to make the shift from DOUBT to DO. In addition to providing hope, inspiration, reassurance, and encouragement, the book offers a clear strategy, plan, and practical tools to help you on your transformational journey from “impossible” to “possible.

In Part II: Your Transformational Journal, the prompts are designed to help you go deeper, reflect on the insights you gained, consider what questions it brings up, and what further research would be helpful as you Navigate Your Path to Possibility.

This book is for you if you are ready to say, “Hell, YES!” to what you really want and create new possibilities in your life.

O’Sullivan’s brisk, upbeat debut shares her methods for making meaningful change in life, drawn from a lifetime as a proud “disrupter” dedicated to turning “the ‘impossible’ into the ‘possible.’” Part memoir, part self-help guide, and part journal, From Doubt to Do finds O’Sullivan (and several women she has profiled) sharing key moments from her experience, demonstrating how she learned to believe in her own “magic” to make transformation possible in seemingly impossible situations. Her tone is sunny and encouraging, at times even irreverent (“When people do ask me where I graduated, I reply, ‘MSU,’ as in, ‘Make Stuff Up’—the school of experience and results”).

As she cheers readers on to face their own desires for change equipped with the four “C”s (courage, clarity, commitment, and capacity), O’Sullivan shares inspirational quotes from sources familiar in the genre (Steve Jobs, Dale Carnegie) and some welcome wild cards (Lady Gaga, Beyoncé). Her goal, she notes, in chatty prose, is for the book to be both rousing and practical, showcasing two keys to change-making and seeing yourself on the other side of challenging situations: “the courage and a roadmap to say, ‘Hell, YES!’” O’Sullivan’s zeal for life jumps off the page as she shares her journey from a child born into mysterious circumstances, to a teen that wanted to perform with a traveling group of inspiring performers, to using what she refers to as “The Bob Hope Method,” which “is about believing the seemingly impossible is possible and being brave enough to ask for what you want.” (Rest assured, younger readers, she explains who Hope is.)

Throughout, she balances actionable steps for change-making with breezy accounts of putting them into practice. The book is quite literally colorful, especially in typography, though some all-caps passages can feel unintentionally shout-y. Still, she charmingly invites readers into her world and encourages them to participate in things that wow and excite them as she does.

Takeaway: Upbeat and positive self-help memoir and journal encouraging change-making.
