Existential Moment

My existential moment is whenever I watch Horton Hears a Who. It makes me wonder if our whole existence is just a speck in the lives of someone else. Is there something bigger than our existence? It makes me wonder if there is an unbelievably large spectrum of unknown in our daily lives, that we have no idea about and no way to figure out. What if there is more universe beyond our solar system, and it just keeps going on forever? Does existence go on forever in all different directions?

The Great Gatsby

"So we beat on, boats against the current, borne back ceaselessly into the past."
I think this is saying, that no matter what, life goes on. Throughout everything that happens in life, we still some how manage to beat on. Against all the hardships and struggle, we still manage to go through life. But I also think it is trying to say that our past will always be with us. People always say to not dwell on the past, but it will forever be a part of who we are and will continually shape us.
