"So why do I harp all day about respect, and write books and blogs about it? Because I want every girl to reach her potential. I want every girl to value herself more than all the bling in the world. I want every girl to be safe and to heal from the bad-dark stuff that happens. I want every girl to discover what one of my teacher's calls your "soul wisdom." In other words, I want you to know the real you and to be all in love with you. I want you to know how to stand by and for you. Then you can spread your yummy amazingness to the world. The world *needs* you to make it. It needs you to blow the lid off this mutha (in your own way, of course)! And it starts with respect on the inside." - Courtney Macavinta, co-author
