Never underestimate the power of brevity. Keeping your message short and sweet increases the odds your audience will stick around to hear everything you have to say. As demonstrated in this article and others, many readers don’t make it past the headline of an online article-- let alone if they have to scroll down the page.
Offline, too, brevity can grant you an air of confidence and competence-- whether in a presentation, press conference, or interview. The trick is knowing when you do need to go into detail: some complex issues or crisis events may require more than 140 characters on Twitter.
Find the sweet spot between rambling and a paucity of information, and your message will come across loud and clear.
