The Day You Became A Better Writer

I went from being a bad writer to a good writer after taking a one-day course in “business writing.” I couldn’t believe how simple it was. I’ll tell you the main tricks here so you don’t have to waste a day in class.
Business writing is about clarity and persuasion. The main technique is keeping things simple. Simple writing is persuasive. A good argument in five sentences will sway more people than a brilliant argument in a hundred sentences. Don’t fight it.
