Faith is the substance of things hoped for, the evidence of things unseen- Apostle Paul.
Heaven is a concept special to certain faiths, not all faiths have the concept of heaven. No one is forced to go to heaven, just as no one is forced to truly believe in Jesus. The problem however is the concept of hell, in most faiths (Christianity, Hinduism, Buddihsm (i spelled it wrong), Islam, and so many more) it is a choice between heaven and hell. No one that is being serious will choose to go to hell if they truly realise what kind of choice they are making.
If you dont want to go to heaven, then you have made you choice. Its up to you to where you'll be in the afterlife. Unless you faith defines the afterlife in a different manner.
