The end of your article is one last final opportunity to catch and keep the attention of a reader. Don’t screw it up.
The sad thing is that the closing section of an article, sales letter, or an email is usually an afterthought. It’s something we writers rush to get to, and then we wipe our hands clean when we write that last word.
That’s unfortunate, because your closing is the one last opportunity you have to flag down a reader barreling through your article.
