Metro-verted

I sat in on a seminar today. It covered in short detail some of those annoying personality test things. It was based on a national personality test thing called "colors". Those things always annoy me because i never seem to fit into one box. Others struggle because they havent had or dont have the ability to analyze themselves, so they tend to score themselves incorrectly or they score themselves as they want people to perceive them. When i try and answer the questions honestly i tend to fall mostly on the introvert side. I find that im extroverted in different settings, though. At work i think im extroverted. As a public speaker/teacher, i display mostly extrovert qualities. I want to be an extrovert, without the obnoxious qualities that typically accompany the type. On the inside, i much rather enjoy being alone, being quiet, thinking, analyzing, and avoiding small talk with new people. I think, bottom line, that i am both, can be both, but left alone without the challenges of work, society, etc, im an introvert at heart. Or does the recent lack of serotonin play a role. When its firing, im extrovert, when its not, im most comfy, at home, by myself, with my own thoughts? Perhaps im "bi" or a metro-vert.
