"We assume if we've heard something, we know it, and if we know it, we are acting upon it.
But people constantly repeat advice because all of us constantly ignore it.
This fact is actually a phenomenon: It's a form of magical thinking. We believe that when we hear something, we learn it, and that once we learn it, we believe we act on it.
You find a parallel to this in at least three-fourths of all companies. They have made a plan. Because of this, they believe they are executing the plan.
But knowing is not doing. And knowing and thinking never is enough.
So if you believe you have heard it before, you have. But ask yourself, and then answer with brutal honesty, the question: Am I acting on that knowledge?"
