How to lead a life to be in Heaven?

Religions that speak about heaven differ on how (and if) one gets into it, either in the afterlife or while still alive. In many religions, entrance to Heaven is conditional on having lived a “good life” (within the terms of the spiritual system) or “accepting God into your heart.”
Doing good includes both big and small things, from donating large sums of money to charities to holding a door for someone or helping someone smaller than you carry heavy items.
