When I say that the fate of any group enterprise, and the individuals within it, are interconnected and interdependent, it may sound trite. But it's not. What's more, seeing all of the interdependencies that shape our lives is impossible, no matter how hard or long we look. If we don't acknowledge how much is hidden, we hurt ourselves in the long run. Acknowledging what you can't see--getting comfortable with the fact that there are a large number of two-inch events occurring right now, out of our sight, that will affect us for better or worse, in myriad ways--helps promote flexibility. You might say I'm an advocate for humility in leaders. But to be truly humble, those leaders must first understand how many of the factors that shape their lives and businesses are--and will always be--out of sight.
