Grammar and style: It is the rule that in any language expression and English is not an exception, it is inherent that correct grammatical expression is ensured.If you can, break the rule in instances where it is necessary. Like in some poetic expressions where this is a common sight. Style, which of course, cannot be alienated from grammar, in that they are inter-related, the important idea is ensuring that a piece of writing is clear and consistent. Ensure a guide for grammar and style is within reach when doing your writing.

Credibility or believability: This is necessary as it has to do with facts and truth about figures, names, events, places and the likes. If one gets this wrong, then the purpose for which the writing is done may be forfeited. This is worse in nonfiction (real and testable events, ideas etc), where the story must be believable, even if it is impossible.In nonfiction, accurate research can make or break a writer.

Thought-provoking or emotionally inspiring: This has to do with the reaction of the readers to the write up. Do they have a fresh perspective or new ideas as a result of reading? Is it enough to make the reader close the cover with tears in his eyes or a sense of victory and etc? This is a key point to know whether a writer has achieved success or not.

It is important to state here that for the sake of originality, nothing is really new in the sense that everything has been done at one time or the other and what we have now might be a remix.Nevertheless, creatively reordering of ideas in a way that it commands newness is a wonderful skill to behold and cherish in literature.
