I believe confidence is all about being positive concerning what you can do -- and not worrying over what you can't do. A confident person is open to learning, because she knows that her confidence allows her to walk through life's doorways, eager to discover what waits on the other side. She knows that every new unknown is a chance to learn more about herself and unleash her abilities.
