Simple Writing Takes Time, Effort and It’s Worth It

Albert Einstein said, “If you can’t explain it simply, you don’t understand it well enough.” Actually, he wrote more than that, but this simpler version makes the point. It’s tough for people who know lots about something not to get lost in the minutia and nuance of what they know. But it’s not in your best interest to let your ego take the lead in your writing; rather, let the audience take the lead in what you write and say. The more you learn about them the better you’ll communicate in their language and at their knowledge level. You’ll both win.
