As girls and as women, we are made up of so many different things. We are our DNA, and we are the hormones that course through us. We are the vitamins and minerals we eat, and we are the fears and concerns we have about what we eat. We are the insecurities we have about not looking right and the thing we do to try to feel right. We are the books we read and the ones we don't want to read, too. We are the love we feel when we hug our best friend, and we are the tears we cry when someone we love won't love us back. We are grief and sadness, and we are the things we do to try and make sense of a difficult world. We are the actions we take to change the things we see that are unjust, and we are as many possibilities as there are stars in the sky. We are bodies that work, brains that learn, hearts that love, souls that struggle and women who matter. We are strong, smart and spectacular. We don't have to be superheroes to be all of the things we want to be. We just have to be us.
