The first two rules of writing are

1) Have a point

2) Make it

It really doesn’t matter what you are writing and the writing style can be high literary or journalistic but a reader should always leave your words knowing what you meant to say. 

A short piece such as a blog post might only have one main point or “argument “.

A longer piece of writing, an essay or a review might have several but each should be clear, complete and come together in a final paragraph or conclusion. 

You see, people need to be able to follow your train of thought in order to decide whether they agree with you or not and that requires clarity. So part of every edit should be a review of your argument. What are you trying to say? Did you say it?

Don’t let people ever decide that you are pointless.
