This attitude is RARE amongst your age group
I think that's one reason I am glad I went to such a good school. Coming from a high school where I could coast to a top college filled with bright students (many of whom could have coasted through high school but instead chose to work really hard) meant that I wasn't going to go on thinking I was the best. Even if I worked as hard as I possibly could, I still wouldn't have been the best.
