There's been a trend on
/r/TrueAtheism (where the non-asshole atheists hang out) of young ex-muslims coming to terms with death being the final ending. Here is my response:
Your immortality is no longer your soul going to Heaven, or its analogue.
Your immortality is your legacy. The memories that will be left behind of you.
DO NOT BE IMMORTALIZED AS A DICKHEAD.
Be immortalized as a mentor, as a thinker. Be immortalized as someone who gave a damn about his community. Be immortalized as someone who wasn't afraid to admit when you were wrong, so that you could actually be right the next time. Be immortalized in your creations, and in the people you have influenced.
BE IMMORTALIZED BY BEING A ROLE MODEL.
