It's simple, yes?

We are born to live and in living eventually die. What we do during life makes no difference to us after we are gone, so far as we know. Therefore, in life we find reason to do. In doing, we find purpose. In purpose we find contentment. In contentment we find peace.

Thus life is just a goal to live the best we are able and find ways to be content in that life. This is why there isn't a universal answer: What contentment looks like changes from person to person.
