I doubt that. It would be nice, but I think it is one of those sayings that mislead people.
Not that there aren't other rewards for doing what you love. And perhaps those are worth more than money. It would just be nice to be able to trade some of those "other rewards" for food, rent, gasoline, etc.
It might also be a good thing if you could tailor your "loves" toward things that can also bring in money. If that is possible for you.
Just something to think about, for what it's worth.
