In communication, clarity trumps everything and most of all cleverness. Clarity determines the style, the length, the time and mode of communication.
This is true in other areas as well. As a programmer in my “other” life, I learned early on that if you use smart logic or lines of code to accomplish some tasks, ensure that you comment in detail because when you’ll see that code after few weeks, you’ll have a tough time figuring out what it does.
Clarity brings purpose into focus and enhances engagement. True for clients, true for life.
