There's no single formula for a great talk, but there is a secret ingredient that all the best ones have in common. TED Curator Chris Anderson shares this secret — along with four ways to make it work for you. Do you have what it takes to share an idea worth spreading?

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less). Look for talks on Technology, Entertainment and Design -- plus science, business, global issues, the arts and much more.
