The Good Place. I watched it during an existential crisis to confront my fear of death. It totally changed my mind! Now, I am too comfortable with the idea of death, and sometimes want to end it faster. I'm getting too tired and depressed to watch climate change slowly consume the world.
The Good Place helped me understand that being a good person isn't necessarily about being good all the time. It's about being a better person than you were yesterday, for the right reasons.
I listened to Mike Schur's audiobook about what he learned about moral philosophy in the process of making the show, and that really influenced my thinking and behaviour as well. Really worthwhile.
Well, don't forget that the Good Place is fiction. There's nothing waiting for you after this except nonexistence, so cling to life and claw every ounce of experience out of it while you can!
