I've read the book. I actually disagree with Cal on the that one for the simple reason you can be really, really good at something and not passionate about it. I think there's a trick here though - get really good at something and then use that to make someone else's life better - now that is something you can probably get passionate about. This whole passion debate will run and run though - I don't think anyone really has the definitive solution - it will be different for different people.
