Do you live in the past, eat leftovers for every meal, live all of your past experiences over and over and never experience anything new? So you fucked up in class. Think I haven’t done a hell of a lot worse? I just say shit, wish I hadn’t screwed that up and move forward. Life is learning from your screw-ups, and moving forward. Heck, if we were supposed to live in the past our eyes would be in our ass so we could see where we’ve been. You can do this.
