One of the first things people usually ask me is, “Gabourey, how are you so confident?” I hate that. I always wonder if that’s the first thing they ask Rihanna when they meet her. “RiRi! How are you so confident?” Nope. No. No. But me? They ask me with that same incredulous disbelief every single time. “You seem so confident! How is that?” …
What I would say, is my mom moved my brother and I to my aunt’s house. Her name is Dorothy Pitman Hughes, she is a feminist, an activist, and a lifelong friend of Gloria Steinem. Every day, I had to get up and go to school where everyone made fun of me, and I had to go home to where everyone made fun of me. Every day was hard to get going, no matter which direction I went. And on my way out of the house, I found strength. In the morning on the way out to the world, I passed by a portrait of my aunt and Gloria together. Side by side they stood, one with long beautiful hair and one with the most beautiful, round, Afro hair I had ever seen, both with their fists held high in the air. Powerful. Confident. And every day as I would leave the house… I would give that photo a fist right back. And I’d march off into battle. …
“How are you so confident?” “I’m an asshole!” Okay? It’s my good time, and my good life, despite what you think of me. I live my life, because I dare. I dare to show up when everyone else might hide their faces and hide their bodies in shame. I show up because I’m an asshole, and I want to have a good time. And my mother and my father love me. … So when you ask me how I’m so confident, I know what you’re really asking me: how could someone like me be confident? Go ask Rihanna, asshole!

So where is the line between confidence and a bit sociopathic? Is it a bit of not caring about others that allows confidence? Is that why so many business people, salesmen, and the like are such a bunch of sociopaths?
