The Talk is on the invisible forces that motivate people's behavior. Robbins, one of the most famous motivational speakers, is saying that while he is excited to speak at TED, it will be difficult for him because the brief TED Talk format deviates significantly from his standard mode of presentation -- days'-long seminars.
