Everybody has to be somebody, someone unique from all the rest of us, all 7 billion on the planet as of October 31st. Seven billion unique identities, individuals, common in many ways of being human and still different in many small ways of being a person. No one like ever before or will be again.
A moment of existence in time and then a memory in history, forgotten in the billions of everybody else. The best we can do is just be and leave the rest to life as we have no idea what's ahead for us, only what has been. Our experience and memory of everybody else we met. It's all we have, like all the other 7 billion today.
