>It's actually a lie that passion makes someone interesting.
Truth. You having a passion for something that interests a person will make you potentially interesting to that person.
People are only interested in a small set of things that they're capable of being interested in. If you show them a new potential interest too far from their existing interests, the amount of passion you have for the new interest does not affect people's reaction to the new interest in a positive or negative way.
If they're interested in the thing, your passion will make them feel more positively about you. And if they are disinterested in the thing, your passion will make them feel disgusted towards you. Many a man with a Star Wars figurine collection has experienced this. Normies cannot look at such a man with any compassion or empathy. Just rejection and disdain.
Good luck passionbro.
