Two quotes from two of my favorite writers have changed the way I think about writing.
"Find a subject you care about and which you in your heart feel others should care about. It is this genuine caring, not your games with language, which will be the most compelling and seductive element in your style.” - Kurt Vonnegut
"This was the old slap-on-the-fingers- if-your-modifiers-were-caught-dangling stuff. Correct spelling, correct punctuation, correct grammar. Hundreds of rules for itsy-bitsy people. No one could remember all that stuff and concentrate on what he was trying to write about. It was all table manners, not derived from any sense of kindness or decency or humanity, but originally from an egotistic desire to look like gentlemen and ladies. Gentlemen and ladies had good table manners and spoke and wrote grammatically. It was what identified one with the upper classes." -Robert Pirsig
