1. Never open a book with weather.
2. Avoid prologues.
3. Never use a verb other than "said" to carry dialogue.
4. Never use an adverb to modify the verb "said”…he admonished gravely.
5. Keep your exclamation points under control. You are allowed no more than two
or three per 100,000 words of prose.
6. Never use the words "suddenly" or "all hell broke loose."
7. Use regional dialect, patois, sparingly.
8. Avoid detailed descriptions of characters.
9. Don't go into great detail describing places and things.
10. Try to leave out the part that readers tend to skip.
On the other hand, here's an excerpt from a Paris Review interview with Philip Roth, so the interviews do deepen a list of tips--just a bit:
"Beginning a book is unpleasant. I’m entirely uncertain about the character and the predicament, and a character in his predicament is what I have to begin with. Worse than not knowing your subject is not knowing how to treat it, because that’s finally everything. I type out beginnings and they’re awful, more of an unconscious parody of my previous book than the breakaway from it that I want. I need something driving down the center of a book, a magnet to draw everything to it—that’s what I look for during the first months of writing something new. I often have to write a hundred pages or more before there’s a paragraph that’s alive. OK, I say to myself, that’s your beginning, start there; that’s the first paragraph of the book. I’ll go over the first six months of work and underline in red a paragraph, a sentence, sometimes no more than a phrase, that has some life in it, and then I’ll type all these out on one page. Usually it doesn’t come to more than one page, but if I’m lucky, that’s the start of page one. I look for the liveliness to set the tone. After the awful beginning come the months of freewheeling play, and after the play comes the crises, turning against your material and hating the book"
I'm sure Elmore Leonard might have a snappy retort for Roth, like, never open a book with weather, which is a sort of literary koan if you think about it.
