At first, I was saddened when I realized that life has no meaning, there's no god, no cosmic alignment. Nothing I do matters in the long run, we are just noise in the fabric of space.

...Then, I eventually felt unburdened. I started doing the things I was afraid of doing at first, because nothing matters anyway right? I can write a story and let it be forgotten, who cares what I wrote if it will eventually be forgotten through the passage of time? It was rather liberating.

I would say, just relax, have fun and enjoy every second of being a noise in space.
