At the top of the list was the directive: Be a storyteller. That's the current meme in communications. Unfortunately, there is less information out there on the how-to of storytelling.
The key fundamental on that is self-editing. Or, as in this author's case, reaching out to a professional editor. Storytelling, like every other form of communications, is an art. That means it requires a lot of shaping. In that process there will usually be plenty of deletion and addition. And in this era of short attention spans, less is more.
In the beginning of learning to tell stories, more will end up on what might be thought of as the cutting room floor than in the final. Every incident and every word of that story should be a needed workhorse, pulling the narrative forward.
To get better at this, view TED talks. Analyze how quickly the speaker gets in and out of a narrative. Practice writing a brief story on the same subject. Do that in several ways. Edit each one. Then make a list of what are the core components of a narrative that is sticky.
