Why is kryptonite dangerous to Superman? It weakens him and deprives him of his supernatural abilities. In other words, it makes him ordinary, like a “normal” guy, destructible, conquerable.
As long as he is Superman, and retains his special talents, he thrives and soars above all else. He dominates in his domain and is unstoppable. His demise can only come when he disrobes himself of his “specialness”, and becomes average.
His averageness is his waterloo.
What sets you apart as a person is what sets you apart in the world, and brings you to a place of success and honor.
Humans, as similar as we are in our DNA and other biological makeup, we are also very different. Our similarities are obvious, and are on the surface. One needn’t do anything to partake in the biological qualities, one need only breath, exist. On the other hand, the things that set us apart are hidden, and we must dig deep, and draw them forth. We must be well-acquainted with our inner, deeper, hidden self. We must intentionally bring forth these differentiating gifts. This takes work. It takes self study, self-knowledge, and self-possession.
A man who knows not himself can not know the vast riches that are housed within him. And so, he can not know what makes him different, special. He is thus undistinguished, and unsung.
Among his contemporaries, he remains a nobody, for he hasn’t found a way to demonstrate his genius, to announce himself to the world, and to stand out . No one goes to the marketplace to buy the things that they already possess. People purchase the things that they lack. People need you for the things that they can’t do for themselves, that is, they need you for the things that make you different. If all you have to offer is what they already have, then you add little or no value to them. This invariably renders you useless.
Become a superman in your area of endeavor. Retain your supernaturalness. Be special, and share your specialness with the world. This is how you win. This is how your soul is fulfilled.
This is a well-lived life.
