We all need to edit what we write, be it a book or a blog post. Sometimes people do that as they read their creations and sometimes they prefer to mark whatever is wrong without fixing it and return to it later.
If you are the latter type, try using different colors to mark the different things that need your attention.
For example, a word in red could mean that something is missing and you need to fill it out later (“We are going to have a blast. *NAME* is tagging along too.”) and a word in green could be a term you often use and need to find a synonym to avoid repetition. You could also highlight the word. Or you can use a combination of both. I usually color one word, but when a whole paragraph needs editing, I highlight it.
