I strongly agree with the importance of your question! It affects so many things, like prioritizing, finding peace etc.
I suggest A) if you are religious, to come to know God and follow His plan, and B) if not, consider working to elevate mankind by honesty, the Golden Rule, learning and service, to help by kind example and teaching and work so we all reach some better state.
