Most people would answer this as they would repent, ask for forgiveness from people if they had done anything wrong to them, would try to do good deeds, would spend time with family, would try to make Him happy etc etc but see this is the question we all should ask ourselves every day but why don't we? Because when one dies it's the end of the world for him and one doesn't know when is the end for him. Still we never ask this question from ourselves!
