Someone who believes they're going to grow up to be a nurse, doctor, lawyer, rapper, singer, athlete, or any other high paying job, but they really grow up to be another typical fuckboy, thot, pornstar (get paid great but is a very disrespected job), work at a fast food joint, or any other low-paying job.
Trying to set somebody who's already straight straight is like trying to drive somebody who's already crazy crazy, it doesn't work.
Start by setting yourself straight and being concerned about your own life, its less futile than always trying to set the world straight. The people who try to set the most people straight are usually the people in most need of being set straight, since they usually never got set straight by their own fathers (or mothers) with an ass whooping every now and then.
