I think this works for some things. Like I hide that I like kind of girly music sometimes:
But I've slowly been showing other people. Same with the enneagram MBTI, I tend to hide those thoughts, I have shown people I know, and they find it interesting... but I don't want to appear as obsessed as I really am, lol. Anime I hide too sometimes. It's just too fluffy to some people, and I don't want to be associated with it. It's good to be yourself in this sense, if you like something weird, or do something weird you should be open to others as opposed to secretiveness and withdrawing all of your thoughts.
But if you try to become more yourself, and you're very schizoid, bossy, scattered, obsessive, disciplined or narcissistic... then you're obviously going to find yourself with a problem. You're going to become unbalanced and you develop problems.
Oh, and sometimes I wear overly formal clothes to uni because I like them, lol. I have a favourite t-shirt, black pants and belt. It looks so flashy . People always ask me why I wear it because it's different than my more comfortable clothing, and they tease me saying that there must be a girl I'm trying to impress lol.
