The real sting here isn't permission to be mediocre—it's the reversal of how we usually think about readiness. We assume greatness arrives fully formed, that someday we'll *feel* ready enough to begin. But Ziglar cuts through that lie by making the starting point non-negotiable: greatness isn't a destination you reach by waiting; it's a direction you enter by moving. When a person finally launches that novel, business, or fitness routine despite trembling hands and doubt, they're not suddenly transformed—they're simply collecting the specific failures and small victories that only motion provides. The quote matters because it collapses the false wall between "not yet good enough" and "good enough to try," and insists that wall never existed at all.
