It's not that you have to have the passion in place before you can engage. Passion is just a pointer to an activity where you are most likely to be present in what you're doing—to really be there simply because you love that thing and so you're completely engaged. It's really the being there that matters, not the passion itself.
I often tell people, "You could be cleaning bathrooms and be completely present in that and loving every moment of it." Most of us don't think of bathrooms in that way, but it's absolutely possible! The word passion indicates a full engagement or wholeheartedness, the wholeheartedness of being in the moment of whatever is happening. You could say it's more about the process of being in what's happening than the specific content of what you're doing.
We each have a collection of ideas about ourselves and we've mistaken that for who we really are.
