Particle physics tells us there are sub-atomic objects so small they cannot be observed until after they have collided with each other, after which they cease to exist. The same principle applies to the line between business success and failure. As long as your business is still in business, the difference between success and failure is undetectable. While you breathe, you can fix things. Only after the company has expired does failure come to seem inevitable — a thick black line of hopelessness that appears only in hindsight.
