The ablest writer is only a gardener first, and then a cook: his tasks
are, carefully select and cultivate his strongest and most nutritive
thoughts; and when they are ripe, to dress them, wholesomely, and yet so
that they may have a relish.
~Augustus William Hare and Julius Charles Hare, Guesses at Truth, by Two Brothers, 1827
Be obscure clearly.
You have to resign yourself to the fact that you waste a lot of trees before you write anything you really like, and that's just the way it is. It's like learning an instrument, you've got to be prepared for hitting wrong notes occasionally, or quite a lot, because I wrote an awful lot before I wrote anything I was really happy with. And read a lot. Reading really helps. Read anything you can get your hands on.
