In which I ponder my individual existence

I wonder how many people think the same way I do. I wonder why I think the way I think. What is an intelligence? How does this short mortality and what I do in it more important than what I've made myself throughout eternity? What is the purpose of diversity? I believe that God made diversity on purpose, that we need to be different. How can everyone in the Celestial Kingdom be perfect and yet still different? How does that even work? How can we not judge? How can we tell truth outside our own personal perspective?
