You're right that the "do what you love" advice is crap. However, I think -- and as Chubot points out -- you have to also avoid the same behaviors as others and offer something "rare and valuable" if you desire money. For those people that you can point to, do they offer the latter and do they have a good sense of when to cash in?

This post from Cal Newport elaborates further[1]. I highly recommend his book So Good They Can't Ignore You.
