I would hope we'd all live our life differently even if we DON'T know - but then I'm not sure what you're looking for. What I am getting at is just that at some point, it becomes kind of boring if you continue to live the same way - generally speaking. Certainly there are those who kind of dig deeply into one thing and I think that kind of dedication to say make something your life's work is great, so it kind of depends on differently from WHAT. Maybe some people are already doing that, maybe some people tries to make their own little paradise now in their life. Hopefully it's at least differently from how everybody else lives, just in terms of not following the crowd to fit in. It's been said, from non-JWs but clearly people who are convinced of this view that even paradise gets a bit boring after a few incarnations. Perhaps somewhere in there is the question of how easily amused the person is. While some want to engage the world at large, others are happy with a really good gaming console.
