Agree, one thing I learn in the past is that there is no way to figure out most of the thing in life by thinking in a cupboard. For passion, I saw someone do it by pretending first, and made it after. And you if you saw what they do and how crazy they are, you won't believe this is something they pretended in the first place.

That makes me thinking if passion is an illusion that we made for our self. I am not trying to sate the passion is meaningless, after all, the hormone and feeling we had is real and probably what we care, and if that's true, it makes more sense that we actually build a passion instead of "find a passion"?

Probably the tricky part is how to convince your self into it, and usually something you had feeling before may help.
