Or yet in wise old Ravenclaw,
if you've a ready mind,
Where those of wit and learning,
Will always find their kind;

The cardinal traits of Ravenclaw are intellect, wit and openness to experience. They are the most introverted house of the four. Ravenclaws are more likely to prefer small gatherings of like-minded individuals and require recooperation after stressful social interaction. These individuals are intuitive creatures, the quintessential researchers. They lack the stubborn, strict, and rule-abiding qualities that would inhibit intellectual growth—one can't be too set in their ways if they are to be open to exploring new ideas and paths of thought.In contrast to Slytherin and Gryffindor, Ravenclaws in general are much more emotionally stable. Their reactions seem dampened compared to the sometimes dramatic responses of the other houses—they're much less likely to get offended, they're more open to criticism, not particularly argumentative and interested in hearing different points of view. They can at times seem to be less interested in people and more interested in their own inner world, and appear to be disconnected from the rest of humanity.

Ambition is secondary to them. Although they may strive to excel in school, knowledge and self-enrichment is the primary goal as opposed to simply wanting good marks. If they do happen to strive for excellence, it is because it fits with their other goals, not out of a desire to be superior or the best. Due to their intuitiveness and willingness to listen, Ravenclaws can be empathetic and make good advisors. They should generally leave leadership roles to people who are more extraverted and who would enjoy them more, however.

"The Dark Arts are many, varied, ever-changing and eternal. Fighting them is like fighting a many-headed monster, which, each time a neck is severed, sprouts a head even fiercer and cleverer than before. You are fighting that which is unfixed, mutating, indestructible."

You are Severus Snape, the Potions Master and eventual Headmaster of Hogwarts. Professor Snape is cold, calm, and calculating. He prefers to roam the world alone and unloved, for the only woman he ever loved married another. His bitterness stems from Lily’s rejection, and the fact that he couldn’t save her from Voldemort adds to his endless grief. Not to mention she married his worst enemy - talk about a slap in the face! As a spy, he is the ultimate dark protagonist, much like Batman or Beatrix Kiddo. It is impossible to deduce what he is feeling or thinking because he rarely ever reacts to situations. You are similar to Snape in the sense that you are both angry individuals. You tend to hide from people rather than embrace them in friendship, and you do not tolerate being talked down to or belittled. What people don’t know, however, is that you are merely wearing a mask. The hard shell that surrounds you is there only to cover the anguish you feel on a day-to-day basis. Secretly, you are a lover, but the pain of life has condemned you to a cynical perspective. I suggest that you take a long hard look at what's really bothering you, and do whatever you can to heal yourself. Whether that means taking a vacation, going skydiving, playing video games, calling up some friends to go see a movie, it's up to you. Do what makes you happy, and don't let the world get you down!

In short, you are more:

Cautious than impulsive
Mature than immature
Arrogant than modest
Normal than weird
Introverted than extroverted

Your polar opposites are Fred and George Weasley.
