The Story: Follow Ernest Hemingway's Four Simple Rules to improve your copywriting (or any writing, for that matter).
The Point: The more effusive and melodious your prose, the greater the certitude you will obfuscate the concept you are laboriously attempting to elucidate; eschew obfuscation.
The Resource: The Elements of Style
1. Use short sentences.
2. Use short first paragraphs.
3. Use vigorous language.
4. Be positive, not negative.
Note: I have written about Papa's rules in the past. This time I decided to do a little research before doing the podcast, and found different versions. So who is right? I don't know. My favorite version, though is at Brian Clark's Copyblogger site.
