Gryffindor?

True Gryffindors have a very strong sense of what is right and what is wrong, and this is a part of what gives them such strong opinions. Depending on the person, this may be taken to a Borderline degree, and they may see people as either good or evil, not in between and no chance of redemption for those on the darker sides of things. Alternately, Gryffindors may see all people as being initially good, and only making the wrong choices take the down the wrong road. Both of these behaviours are why Gryffindors and Slytherins can easily clash. Gryffindors are usually incredibly intelligent, but they tend to be slackers, more focused on getting a taste of something new than sticking to responsibility. This can be their downfall from success, or quite the opposite, bringing them a rise up into something they love. Once they find their true place in the world, Gryffindors will often use their accomplishments to the benefit of others in some form or fashion. Actors, singers and athletes can often be classified as Gryffindors. Despite their good intentions, they can also quite often be ill-tempered and overly emotional, which is their Achilles’ Heel in most instances. A darker Gryffindor may become out of control because of this, hurting those they love or holding a grudge for many years.

Hmm,this does actually sound like me....Maybe...maybe the Hat did get it right...
