I think if we had a deeper appreciation of life, it wouldn't be taken for granted so often.
Well quite. Its knowing that this is the one life we all have that makes me appreciate it, and try not to make it worse for others. By contrast, those for whom this life is a momentary blink on the way to an eternity of wonder tend to be the ones who make this
life worse for people. Belief in an eternal wonderful afterlife can do little other than render this earthly existence seem ephemeral and beneath regard by comparison.
Why take care of your toys, when you know that they will soon be taken away and replaced with toys that are indescribably better? You're right, it is
a good analogy for people and this earth - though it tends to be the most ardent believers who are least appreciative of the here and now.
