To me, the afterlife is the equivalent of how portraits work in the Harry Potter books. I'll no longer be conscious or self-aware and therefore be rid of all the problems those bring. But my 'soul' if you will, shall be preserved richly and intricately in the memories of those precious few whom I have touched, and I'll live on in their dreams, brought back to life in their sleep like a magic portrait. I'll be happy.
It sounds like a sweet metaphor, but it's the core philosophy I live by and it both motivates me to do good in the world, avoiding nihilism and giving meaning to my (painful) life, and also to not fear death.
