No Ma'am

From my understanding, which is limited to say the least, you dream job is supposed to be you passion. It's not supposed to feel like work. I get it, but what do you do if you don't have/can't find your passion? I have no clue. I am in possession of a severe amount of interests and I know a little about a lot, but how do I figure out which of these interests is a "passion." And when I do figure it out, what then?

I'm really lost. I want to write, badly (not poorly) but what to write about? Survival? Preparedness? Superheroes? Sci-Fi? Fantasy? Fiction? Non-Fiction? Inspirational? Haikus? I have no clue.

Advice?

I guess, until I figure things out, this tubby, bearded, Al Bundy type will continue managing a women's clothing store and be drastically underpaid for it.
