When you write an op-ed, a speech, or even correspondence, you begin by asking "What is this about?"
Instead, ask this: What do I want the reader to do after they read it?
All professional communication should create a response in the physical world. If yours doesn't, don't send it.
Even if you're just sharing information, ask yourself why, then tell your readers or listeners what to do with it.
Do you want them to start or stop some effort? Change a habit? Reply? Say so.
If not, consider whether you need to send it at all.
This changed everything for me. Maybe it'll help you, too.
