Writing is risky business. In fact, many authors (I wish I could remember who now) have said that one can only truly know themselves once they write. When your thoughts turn into words they become real, tangible, analyzable, attackable. There is indeed a certain amount of bravery involved in writing, but there are also many mechanical things involved in writing like sentence structure, finding that oh so perfect word, and keeping things snappy.
To take some of this pressure off, there are many writing tools out there to help tighten your sentences, vary your vocabulary and wield your words into art. Fellow colleague Nicholas Walker is the creator of Virtual Writing, a tool that offers many features beyond Grammarly and the Hemingway app. A self-proclaimed virtual proofreader, it is totally free and may even teach the teacher a few things.
