I think at this point, I feel confident that I know what I am as far as these infantilism tendencies go. However, that doesn't stop me from wanting to learn more about myself. I could go in-depth, I could put it in a concise manner; the point is, I know what these interests mean to me.
Now, I realize this is an abstract question, so feel free to go ham on it. Whether these interests bring you pleasure, or a personal trait. Do you feel confident you know yourself?
