bad writing is such a turn off. didactic writing is even worse. and a lot of the crap out there is horrible. the stuff in the best sellers list. most of it is crap. it's too bad that the average person isn't well-read enough to know the difference between good and bad writing.
but a discerning taste cannot be taught. it has to be acquired through reading and observation. one way to go about this is to read classics. like hemingway, or wilde, or dickenson. go into the classics section, learn about prose, learn about the magic of words that when juxtaposed just right can make you cry.
and if you don't know what i am talking about, it's because you haven't let yourself experienced it.
so go read. and let there be better writers in the world.
