You think that maybe if you had taken the time to study more and expand your mind and gain new experiences that maybe you would have been more successful.
You wish that you could go back and do things a different way; not focusing all your attention on girls and beer.
You close your eyes and the next thing you know feel a pair of glasses. You clean them off to notice as you notice that you are standing in the school's library. That's not the only change, as you also notice you've become a high school girl with long brown hair and a neat sweater.
