You're a badass - Jen Sincero
This is a lifechanging book that is highly effective at rewiring the subconscious by Jen Sincero.
A basic fundamental principle of physics and life is that 1) you can’t replace something with nothing, and 2) everything changes.
You’re A Badass does a great job at freeing up the psyche and rewiring the unconscious to align with these principles. This book will change your life. I always recommend the audiobook because you need the vibration of her voice to get the message.
