This is bullshit. It got me so riled up I went and blogged about it: http://calroc.blogspot.com/2014/01/love-is-power.html (It is cool to post links to own stuff in a comment like this? I'm new to HN.)

tl;dr: The idea that you can and should "do what you love and love what you do" arose as a counter to the misguided idea that work is something you hate that you do just to get the money to pay your bills and keep the lights on and the pantry stocked. To confuse the basic concept with a sort of bromide for the blind egos of a privileged elite is a terrible mistake.
