It wont do to say that the reader is too dumb or too lazy to keep pace with the train of thought. If the reader is lost, it's usually because the writer hasn't been careful enough

Vulnerability has a strength of its own.

But on the question of who you're writing for, don't be eager to please.

Writing is such a lonely work that I try to keep myself cheered up.

There are some writers who sweep us along so strongly in their current of energy--Normal mailer, Tom Wolfe, Toni Morrison, William F. Buckley, Jr., Hunter Thompson, David Foster Wallace, Dave Eggers--that we assume that when they go to work the words just flow. Nobody thinks of the effort they made every morning to turn on the switch. You also have to turn on the switch. Nobody is going to do it for you.

I'm often dismayed by the sludge I see appearing on my screen if I approach writing as a task--the day's work--and not with some enjoyment.

The writer, his eye on the finish line, never gave enough thought to how to run the race.

Don't annoy your readers by over-explaining--by telling them something they already know or can figure out. Try not to use words like "surprisingly," "predictably" and "of course," which put a value on a fact before the reader encounters the fact. Trust your material.

Most writers sow adjectives almost unconsciously into the soil of their prose to make it more lush and pretty, and the sentences become longer and longer as they fill up with stately elms and frisky kittens and hard-bitten detectives and sleepy lagoons. This is adjective-by-habit - a habit you should get rid of. Not every oak has to be gnarled. The adjective that exists solely as a decoration is a self-indulgence for the writer and a burden for the reader.
