Are you ready to change your life?

This is a question that coach and podcaster Cassia Tierney Clarke avoided for many years until the point at which she had no choice but to change. Fast forward five years, and she has taken herself from struggling to brush her teeth to running marathons all over the world.

Through her own journey, and coaching hundreds of clients, Cassia learned that small actions create the energy that will propel your progress in every area of life. Starting with the simplest, most achievable habits, Cassia will show you how to build the necessary and life changing momentum you need to move forward with your goals and create a version of yourself you never thought possible.

Whether your goal is to experience new adventures, build the strength you have always dreamed of, or unlock a deeper connection with yourself, this book will gently guide you through each step of the process. In Momentum, Cassia rejects the 'quick-fix' mentality and instead provides the tools to meet yourself where you are. By establishing real foundations, you can create lasting momentum and move forward with a renewed sense of hope.

Woven through with Cassia's unique storytelling and personal anecdotes, Momentum is the book that will not only convince you that you can change, but more importantly show you how.
