follow your bliss vs dont follow your passion

[Viking]

Im reading right now "so good they cant ignore you" and the first rule there is "dont follow your passion". Basically the concept is that what we're passionate about doesnt necessarily will get us the most fulfilling work. on the other hand there's Joseph Campbell that says to follow your bliss into the hero's journey.

I never really understood the follow your bliss part and how do you know what your bliss is, but on the surface it seems like it contradicts the "dont follow your passion" rule. is there a difference between passion and bliss?

It happens quite often that different sources of information give out opposite answers and you never know what to believe. ("believe" because a lot of this is counter-intuitive and cannot be really contemplated alone without falling into some traps I think)
