I think a sentence is a fine thing to put a preposition at the end of.

Don't try to guess what sort of thing editors want to publish or what you think the country is in a mood to read. Editors and readers don't know what they want to read until they read it. Besides, they're always looking for something new.

Never say anything in writing that you wouldn't comfortably say in conversation. Be yourself when you write. If you're not a person who says 'indeed' or 'moreover,' or who calls someone an individual ('he's a fine individual'), please don't write it.

The secret of good writing is to strip every sentence to its cleanest components.

Don't hedge your prose with little timidities. Good writing is lean and confident. . . . Every little qualifier whittles away some fraction of the reader's trust. Readers want a writer who believes in himself and in what he is saying. Don't diminish that belief. Don't be kind of bold. Be bold.

Decide what you want to do. Then decide to do it. Then do it.

Motivation clears the head faster than a nasal spray.
