#life sucks

I'm opening this thread because I've been seeing multiple threads where people complain of the life they live. I don't want to argue whether this life sucks or not because it sucks for most of us. What I want to know though is if the existence of an after life would change your attitude towards this world we are living in.

Keep in mind that I'm not assuming anything about what christianity try to sell us. So, let's say there is no God, no hell, no heaven, no devil, just another parallel world where we come from and where there is no pain, no suffering, just a feeling of absoulute peace, and that we are sent to this fucking world to accomplish a mission: make the human being evolve. So, it's a sort of matrix where you are supposed to live temporarily in order to forge love in you and the rest of the people because it's said that love is the only way humans can evolve. As simple as that.

Would you then change your mind and make your best to accomplish the mission no matter how hard it looks? I read you.
