You want to know what the worst part about life is? It's the fact that eventually, after we die, we're going to choose to come back and do all of this stupid shit all over again. We will be born to parents, deal with pain and suffering, deal with drama in school and in life, deal with struggles, and deal with retarded people. All of it.
The reason we choose to come back to a limited world is that the afterlife is basically infinite. All knowledge, scenarios, experiences, parallel universes, and planets are right at the tips of our senses, consciousness, and mind's eye. Want to have sex with your ideal partner? You can do that. Want to live in your dream home? You can do that. Want to rule your own country or live out a fantasy as if it were actually real? You can do that too.
Heaven becomes a nightmare that will drive you nuts and bore you to the point that you're gonna want challenges and pain. Believe me, I know because I've been through the process so many times, and so have you, just not everyone remembers. You could try to rest in total blackness and nothingness, but that is also technically something, and it's something you will be aware of. Eventually, you'll get bored of that, too.
It's basically this life, then having everything at your grasp, and then this life again, on and on. It never stops. We're fucked. What is this shit?
