Four Cs of Writing
        Clarity: choice of words, arrangement of words in 
          sentence
          Continuity: how sentences hang together, the “glue” 
          that holds sentences together
          Concision: avoiding redundancies 
          Coherence: organizational structure of paragraphs, 
          sections of documents, and papers
          
          
          Clarity:
          Principle 1: Prefer active construction to passive.
          Principle 2: Make your verbs portray action whenever possible.
          Principle 3: Whenever possible, use characters as your grammatical subjects. 
          
          Avoid nominalizations (verbs turned into nouns like evaluation).
          Avoid vague and isolated pronouns (this, it).
          Avoid using there is or there are in your sentences.
          Place your subjects and verbs as close together as you can.
          
          Continuity:
          Achieve continuity through stress, transitions, sequencing, common subjects.
          Principle 1: Put the most important information in the ends of your 
          sentences, paragraphs, sections of documents, and papers.
          Principle 2: Use transitions to glue your sentences together.
          Principle 3: You can foster a still greater sense of flow by using sequencing.
          To sequence information, refer in the beginning of sentences to information 
          contained in the stress of the preceding sentence.
          Principle 4: Make your grammatical subjects consistent from sentence 
          to sentence when possible. (Common subjects are the weakest way of creating 
          continuity. When you use this approach, supplement the subjects with 
          transitions.)
          
          Concision: 
          Principle 1: Avoid redundant pairs. (Ex. each and every)
          Principle 2: Avoid redundant modifiers. (Ex. completely finish)
          Principle 3: Don’t Use No Negatives. (Ex. use "few" 
          instead of "not many")
          Avoid throat clearing modifiers (Ex. "really" or "I believe 
          that") 
          
          Coherence:
          Principle 1: Begin with a paragraph head.
          Principle 2: Back the head up with a paragraph body.
          Principle 3: Head/Body organization applies to: paragraph, section, 
          entire document.
          Principle 4: For complex paragraphs and always for your entire document, 
          you must use a thesis sentence.
