Over the years, since I saw her original TED Talk, I've tried to take Brown's advice to heart. 

There is nothing more frightening than the moment we expose our ideas to the world. In this presentation at the 99U Conference, author and vulnerability researcher Brené Brown shows us how to deal with the critics and our own self-doubt by refusing to “armor up” and shut ourselves off. “Not caring what people think,” she says, “is its own kind of hustle.”

Instead we must “reserve a seat” for the critics and our own self-doubt. “Tell them, I see you, I hear you, but I’m going to do this anyway.”
