Well - here's the key to success, if you've got three minutes to spare. Watch this speech by analyst Richard St. John, where he condenses years of interviews into a really worthwhile slideshow on the real secrets of success.
This video comes from the TED site. This is what they say about themselves:
TED stands for Technology, Entertainment, Design. It started out (in 1984) as a conference bringing together people from those three worlds. Since then its scope has become ever broader.
The annual conference now brings together the world's most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes).
If you've got some spare time (and a good internet connection), watch more of the speeches presented at ted.com. They're all fascinating, and it's a great way to practice your listening comprehension and to expand your vocabulary. Not all of the speakers are native speakers of English, so be careful there. But only great speeches and presentations make their way onto ted.com.
