I am absolutely brooding!

Is it placid darkness or just a quiet calm style that sets you apart?
Virtues: Appreciation for deep thought is important, and no, I don't mean "Deep Thoughts" by good ole Jack Handey, though that must be widely loved. Humor-- light and dark-- is a staple, and absolutely necessary is your art. Literature, music; it's all important to your self expression.
Aspirations: There's a wide range of possibilities for any thoughtful person. Especially common would be artistry; writer, painter, composer; even the comedy field could use some help. If you're interested in politics, maybe a professional cynic would suit. ;) I'm sure you'd like to express your views openly (not limited to politics, but thinking in general) as your views of the human race are vast and intricate. Socrates would be proud.
Quirks: The peppy and preppy, the superficial and the artificial.
Factors: What you need is your downtime; peace and quiet. Relaxing with a good book, listening to some music. Thinking is a big factor, be it sophistic or plainly dark.
Future: As you continue to develop your views, self expression is inevitable. An outlet career aligning with your views would be ideal, and you may even enjoy a family to settle down with. Until then, I'm sure you'll develop your studies and talents to their fullest.
