The 8 secrets of success

This is a three-minute video which comes from TED.com

We all need some listening practice to improve our English, but not only that! 

Would you like to be successful? 

or a millionaire? 

or fulfill your dreams? 

Listen to this video and maybe we learn how!!

Everything he says makes sense to me and I like his humorous style.
But which of the eight secrets of success do you think is the most important? It's probably a combination of all of them, but is one of them more important than the others?
They don't mention "luck", do you think luck is important at all in life? for example, let's say in exams, is luck important?
