I envy people whose passion is useful for others. Most of my passions are totally self-centered and will never produce anything anybody else will be interested in. So following my passion would not make any money.
I would much prefer if my passion was to sell things.
That's the fun though, you need to find a balance. I like video games, movies, and reading. On their own, these passions don't add up to much. Recently though, I've found a good blend - I make video essays on topics I like.
I recently made a video on how Kirby Superstar redefined other kirby games. To do that, I had to play some Kirby (video games), analyze it (a bit of critical thinking), write a script (writing), and put together a video (movies).
Of course, doing this isn't as fun as playing a video game or watching a movie, it still takes hard work, but it's a nice blend of things I like and things that other people like. It's going to take a lot of hard work to get even a part-time job out of it, but I'm committed to making a video every single week.
Everybody is "passionate" about some kind of vice or leisure. But you probably have some useful passions buried in there too. It's a waste of braincells to lament how unfair it is that your only passions (drinking & sleeping) are not very marketable skills.
Drinking is a marketable passion - you could become a beer/wine connoisseur, or something like that.
The worse thing that could happen is to discover - like I did - that your passions are in inverse relation with work. I loose positive feelings about programming and start to stress out pretty much immediately when a project starts to feel like an obligation, which makes me 10x less productive at work than on my hobby projects.
