Life is about the experience. If it is longer, then we get more to experience. This can be both a good and bad thing. Would our standard of living be similar?
I don't care what happens after we die, and so I just leave it as so nothing happens after we die. I think that makes living now more important. If we only get once chance of consciousness, then why not try to make it the best you can? If I believed in something else afterwards, I can fall into the belief that this life doesn't matter because I can do it again.
It's like a student who knows the essay is due next week and it should only take him two days to do it. They are more likely to try and find justifications not to do it ahead of time and just do it two days before it is due. Not all people fall into this trap, but many do. Why put off something today when you can do it tomorrow it seems.
