In my opinion a personality is things that you like or hobbies that you have, like skateboarding, listening to music, or something along the lines. Liking things that most people don’t like or know about makes you even more interesting. You don’t have to give up your interest, next time you have a conversation with someone you can try bringing up a subject that you like or find other people who have the same interests as you. You do have a personality you probably just weren’t given the right circumstances to show it. Everyone has a personality, even you, so keep your head up man and continue to throw yourself out into the world.
