If you are not going to be worthy of the belt that you wear around your waist;
If you are going to just slop your way through every technique and kata, the way you've done, day after week, after month, after year;
If you really just don't want to be in class, and you're soooo bored that you can't even bother to act like you give a damn;
STAY HOME!!! QUIT!!! Don't let the door hit ya' where the good Lord split ya'! GET OUT!!!
You drag the entire class down, provide a crap example of what a higher belt-holder is supposed to be, and you make our whole class look bad.
GO. AWAY. No one wants to look at your face and read how very very bored you are. No one wants to look at your sloppy, half-assed techniques. No one wants to talk to you, since you never speak above a mumble, anyway.
