The problem with the world is not the F students, or even the D students; it's those goddamn worthless, trifling, lazy, almost a loser but not quite, shiftless, mediocre, middle-of-the-road C students.
C students are a problem because they mimic B or even A students. They can easily infiltrate an organization or your life, because they have learned to copy those just above them. I respect the hell out of an F or D student, who essentially has said, "Fuck it." At least they know who they are. C students straddle the fence, and it makes life very confusing.
You know you've run across a C student based on their answers to basic questions. Their responses are always generic, always neutral. You: "What is most important to you in life?" C student: "Living, laughing, and loving." Shut the fuck up. Can you come up with something a little more original? You: "What are your goals in life?" C student: "Just to be happy and be the best motherfatherfriendsistergirlfriendboyfriend I can be." Lame, shortsighted, and insufficient.
This really is a learned behavior. It started with essays in grade school and evolved into interview answers. Interviewer: "Tell me about yourself." C student: "I'm an excellent communicator with great customer service skills." Kill yourself. I'd hire an F student over you, any day.
C students hold the world back because they never choose a side. "Well that's true for some but not for all." Why, thank you, Confucius. That was life-changing, earth shattering information.
Parents, if you find yourselves the proud owner of one of mediocrity's finest, please do us all a favor and just coach them down. They'll be happier that the pressure is off, and society will benefit on the whole. Better yet, if you were a C student, hows about not duplicating your borderline sorry life?
