That's great advice, and when I have time to edit (rare for a spare-time blog post, but required with a book), I start hacking off all those extra words. (Like, "off all those"). But removing words isn't enough. We must insert space. Space for the reader to become engaged.

Space for the reader to reflect, process, and co-create the meaning.

And they can't do that if we're filling all the space--pushing content out like a firehose.

Newbie teachers/trainers often make the same mistake. We fill in every available space, just like those first-time desktop publishers who "abhor a vacuum" and cram words and clip-art into every square millimeter of a flyer.

But real learning takes place between exposures to content! Long-term memory from learning happens after the training. The space between the lessons and practice is where the learning is made permanent. If we don't leave that space, new content keeps rushing in to overwrite the previous content, before the learner's brain has a chance to pause, reflect, and synthesize the proteins needed for long-term memory storage."
