I guess it would be the same for a non believer...who doesn't want to miss one little pleasure of life, because once he's dead it's over.
The believer will be more balanced I think keeping in mind that after this life there is an eternal one.
I see the same thing from a different perspective. The non-believer will try to get as much as he can out of this life, and leave a real legacy because he knows it's all we've got.
The believer will fritter away the precious few years he has knocking on doors, going to church or whatever he believes will get him into the afterlife he desires.
In the end, the result for both is the same, but one has wasted his life.
