I'm think I am an introvert, I probably always have been. I try not to shy away from it anymore because I don't think it's necessarily a bad thing. Also, I think a lot of people misunderstand what introversion means. It can mean "a shy person" but I like to think that the psychological definition of introversion is much more relevant:
"a person characterized by concern primarily with his or her own thoughts and feelings"
This makes a lot more sense to me; I'm not a quite person because I have nothing to say or I'm scared to say it but more so because I'm taking everyone's inputs in and assessing my own thoughts first. I'm the kind of person who doesn't need to have other people around in order to feel happy, energized or active. I'm perfectly content spending a weekend with myself, just going about daily life and reading a book or two (or 10). I like listening to my music and staring into space (or simply staring into space).
