I think the only way you find your passion is by trying different things. I pole dance and I love it so much. I wouldn't know that if I hadn't stepped out of my comfort zone to go to a class. I am also passionate about reading. Dont ever get me talking game of thrones unless you really like it too. Lol.

Find something that looks interesting, fun, different, etc and give it a shot. Keep doing that until you find what you love.
