You Are a Badass: How to Stop Doubting Your Greatness and Start Living an Awesome Life by Jen Sincero
I was drawn to this book for it's obvious reasons of course because, duh, I am a badass and I've never thought anything less of myself but just like you and plenty of other people I forget sometimes and I need refreshing reminders of my badassery. Her book strives to empower any reader to shake of the cobwebs of doubt and to start trusting the universe. To master positive thinking, smash the ego and learn to be present so we can enjoy the life we are building for ourselves. Such a great listen, because hey, I listen to audio books now!
You can find Jen's book on audible, Amazon or if you are vintage like I like to be sometimes you can mozy on over to your nearest Barnes and Nobles to get your hands on a copy.
