You clearly misinterpreted the song.
yeah. i really wanted to run through the halls of my high school and scream at the top of my lungs....
theres no such thing as the real world????
foh
The song is about NOT being the most popular kid in high school, not following what every other kid does, and yet still coming out on top by being yourself.
Basically it's about not being a sheep.
Read those lyrics you posted in the context of the verses and the song itself.
