Neitzche's Rules of Writing.

1. Of prime necessity is life: a style should live.

2. Style should be suited to the specific person with whom you wish to communicate. (The law of mutual relation.)

3. First, one must determine precisely “what-and-what do I wish to say and present,” before you may write. Writing must be mimicry.

4. Since the writer lacks many of the speaker’s means, he must in general have for his model a very expressive kind of presentation of necessity, the written copy will appear much paler.

5. The richness of life reveals itself through a richness of gestures. One must learn to feel everything — the length and retarding of sentences, interpunctuations, the choice of words, the pausing, the sequence of arguments — like gestures.

6. Be careful with periods! Only those people who also have long duration of breath while speaking are entitled to periods. With most people, the period is a matter of affectation.

7. Style ought to prove that one believes in an idea; not only that one thinks it but also feels it.
