I have always thought that Heaven is a place for people who had had a good life, but that is not true. God is merciful and way too good to make it so. The Heaven is just a place for people who could not be really happy while living on Earth. I was once told that people who commit suicide are taken back on Earth to repeat life from the very beginning because if they did not like it once, it did not mean they would not like it the next time. But those who did not fit in on Earth at all, ended up here. Everyone comes to Heaven in their own way.
