Time On Earth

Have you thought about our time on Earth - why we are here, what we have to achieve?

If yes - what is the answer? - Share yours. I will try to formulate mine.

And is it so that all our actions have consequences? - Then why so many people do so much harm to others and not being punished....?

Maybe too many questions for one post. But it is important. Otherwise, we waste our time here. Completely.
