From How to Write Missionary Letters: Practical Tips to Make Your Words Come Alive, Alvera Mickelsen, 1995.
Keep words, sentences and paragraphs short. Sentences should vary in structure and length.
Prefer the simple to the complex.
Use familiar words.
Avoid unnecessary words—cut ruthlessly as if you were an editor.
Use active not passive verbs.
Write the way you talk.
Tie your letters to your reader’s experience. Proceed from the known to the unknown.
Use concrete words your reader can visualize. Abstract words dully our writing.
Add variety. Develop your own personal style.
Write to express—not to impress.
