Straight from one of the best books I’ve read on communication (Trees, maps and theorems by Jean-Luc Doumont), is this paragraph on helping stem the flood of emails. Sage advice indeed:
If you are buried under too much incoming email, you may feel helpless about it. Yet, without hoping for a revolution, you can still take concrete steps toward easing the overload. To receive less email, simply send less email - and send better email, too.
So, starting today, think before you send and if it’s not required, don’t send it.
