Is it better to write long or to write short?
With rule #38, Masello examines that question. In his essay, he cites the story of the man who wrote a long letter and apologized that he didn't have the time to make it shorter. Masello's advice is very simple: when you're first writing, get down everything that you'd possibly want to write. But once you've done that, go back and whittle out everything unnecessary to make your point.
In the spirit of this rule, I will simply say that I agree.
