Personality and uniqueness, absolutely!
I work at a high conservatory and helped a student w/her personal statement. Try to engender yours stand out so that the people contained by power believe that you will be an asset to the school.
Emphasize not just your seriousness about studying and achieve, but also how you are a well-rounded person who will supply to the general atmosphere of the university itself (i.e., bring out any really meaningful extracurriculars surrounded by which you've participated).
Boring and sophisticated is not the way to dance, in my inference.
Wouldn't it also kind of depend on the unique university to which you are applying??
That really depends on the university. I would lean towards personality and individuality if it is something that may be seen as beneficial. Don't give an account them you like to burn inert animal skins int he backyard, but do tell them you similar to doing civil war re-enactments or that you relish helping with political campaign or whatever interest you do that may be see as spmething positive. I agree with the others who own answered you. Personality and uniqueness. To me, you own to stand out from a pile of applicants, and it is important to take in for questioning the reviewers attention from the first line of your statement, so that's probably the most earth-shattering line you'll write. Make it count.
