How honest!?! Seriously... Respect.
The rest of this isn't really directed to you but take it into consideration.

I don't believe in heaven. for 1 reason. "It makes life worse!"
Our current science cannot Prove afterlife exists. (Mind you, that's the first rule of being scientific "1. You must be able to prove it")
I choose science usually, but ALSO people who believe in afterlife are much more susceptible to a less fulfilling actual life. The reason is because the afterlife presents the possibility or assurance(much worse) that "you" will continue to exist.
If you KNEW that you would die at the age 500(assume you will still be healthy and, look young) wouldn't you put off the "important things" until you we're 450? Maybe you would put off the "important things" until you were 499. Knowing or thinking "you" as a soul will not die after death is the same as knowing or thinking you will live longer or forever. Afterlifes like heaven give people the belief they will continue to exist and that naturally lowers their desire to make the most of real life.
UC's chart o' how long "you"(soul or whateva) have to exist
If you think you will stop existing tomorrow (UR PARANOID DOOD)
If you think you will stop existing in 5 years (UR probably depressed or weird)
If you think you will stop existing afterlife (U have a HEALTHY concept of life)
If you think you will stop existing after afterlife (Ur not living for today, and prolly going to miss out)
If you think you will stop existing never (Ur living a dream)
If we're talking about heaven. That's a whole bag o shit. If Heaven is a personal heaven (like each person's own universe) I Say FUCK THAT. I want to be in the heaven with the REAL person. Not a copy suited for me. But that means I'm fucking my REAL friend's REAL wife (in heaven) and that wouldn't be cool with his REAL heaven.
ALL "versions" of heaven REQUIRE us to CHANGE as a PERSON, to EXIST in them. Is that really a "Heaven" and are we really "Ourselves" in this heaven?
A collective heaven is no good and a personal heaven doesn't give us a REAL heaven (it would be fucking simulation).
Conclusion: Heaven is a joke concept, afterlife takes away from living real life, life is scary, but that's part of the fun. Live life for today because its all you got son.
