In the talk Why you will fail to have a great career, held in Ontario (Canada) last year Larry Smith, a professor of economics at the University of Waterloo (Canada) goes over the excuses people come up with when they fail to follow their passions.
This is the information TED gives on Larry Smith:
"Larry Smith is a well-known storyteller and advocate for youth leadership, he has also mentored many of his students on start-up business management and career development. The most notable start-up he advised in its infancy is Research in Motion (RIM), maker of the BlackBerry."
Mr Smith's a really fast talker, so you may need to activate the English subtitles to fully understand what he says. Another option available for you is read the transcript of the talk first on the TED site.
