I think I've figured it out. My real passion is "to create". To limit my passion into a certain category only like "fashion" or "art", or perhaps for you, "music", "drawing", "statistics", seems unfair. It's too simple. As humans, we are complicated, we are multi-dimensional, we love many things, and that is okay. Passion is not the product, it is the spirit that moves you. To create, to help, to entertain, to educate, basically the purpose that fuels you up.
I love creating, and to finally know that, liberates me. I see a world bigger than before. Because creating can be applied in so many new things. And that sounds just exciting.
