转载"Think of your life as a rainbow arcing across the horizon of this world. You appear, have a chance to blaze in the sky, then you disappear.

The two endpoints of everyone’s rainbow are birth and death. We all experience both completely alone.

And yet, most people of your age have not thought about these events very much, much less even seen them in others.

How many of you have seen the birth of another human? It is a miracle. And how many of you have witnessed the death of a human? It is a mystery beyond our comprehension.

No human alive knows what happens to “us” upon or after our death. Some believe this, others that, but no one really knows at all.

Again, most people of your age have not thought about these events very much, and it’s as if we shelter you from them, afraid that the thought of mortality will somehow wound you.

For me it’s the opposite: to know my arc will fall makes me want to blaze while I am in the sky. Not for others, but for myself, for the trail I know I am leaving."
