Jason Fried:

There’s nothing wrong with loving what you do, of course – I just don’t think it’s a prerequisite for starting a business or building a fulfilling career, let alone doing great work. In fact, I think it’s disingenuous for really successful people to put so much of the focus on love, just as it’s disingenuous for really rich people to say money doesn’t matter.

I feel like this is a genre: disingenuous things that really X people say about the importance of X (or thing related to X).
