write a classic

I want to write a novel that will define a generation. I want to write a novel like a hand grenade with no pin, a novel that explodes in the brain. I have piles and piles of tattered diaries of every description, some leather bound, some nothing more than excercise books. In them my words squirm and moan liked trapped eels. Reading back, I see that my writing is deteriorating over the years. I fear that I am eroding the only skill or talent that is promising in my life.

my stories have no bearing on anything important.
i want to write something that people would want to read, soemthing that maybe they would assign to high school students one day.
