Adding words is easy.
But more words don’t necessarily add to more clarity.
As the Occam’s Razor principle implies, you should use as few words as possible to explain – and no more.
More words = confusion.
More words are likely to be filler fluff.
More words = potential to lose your reader or viewer or listener.
You, or someone else has to be kindly brutal, trimming the fat, without cutting into the muscle.
More is less, and less is more.
