The problem with preparing for exams is that usually, you have a general idea of things. Not too little, not too much, but you're still there somewhere. Yet somehow, going through the same bland things over and over again all year, there comes a time when you're so satisfied with the little that you do know that the unknown doesn't frighten you any more. You become immune to its charms altogether. And that perhaps is the most disastrous thing that could happen. Because from that point onwards, there exists an opposing force that resists very much the addition of anything new and variable. An antagonist, if you like that shifts the dose response curve so far to the right that its pushed out of the picture altogether. Of course the blockade does maintain a certain amount of competitiveness, so you try to up your dose a bit. Like a train struggling uphill, huffing and puffing all the way. Only to find someone rushing towards you, frantically waving a red flag, forcing you to slam down on the brakes.
And then you say your prayers, clutch your rails and prepare to tumble down the ravine.
And this shall be the soundtrack to my flashback.
