I know this is going to sound strange.
I killed myself. Or rather, I tried to kill myself. I mean, I did kill myself, but then I was still alive, in a new universe. My memories from the previous universe survived when I woke up here.
It made me realize that I literally cannot escape. Even through death.
That has given me a sort of “burned my ships” commitment to life that has made me truly alive. I also realized that all other humans are also trapped in a quantum immortality situation that will last for eternity as far as I can tell, so my level of caring and compassion for others has also increased.
I know it sounds totally fucked, but by realizing that I literally cannot die, it made me realize how important every moment is. Because every choice is a seed of eternity. The value of doing things right just went infinite for me, and I’ve never been happier, more productive, more generous, more committed to doing things right.
