Fossilized remains show us what living creatures were doing at time of death. We can learn from fossils: climate, diet, relationships, social structures (even of insects).
Chances are, you won’t be an actual fossil. Unless you’re caught up in something really dramatic, sudden and devastating, like the eruption of Mt. Vesuvius in Pompeii (79 A.D.) However, you will leave a legacy. What will it be? Works of art? Enlightening music, film or novels? Or a career of corruption? Maybe you will leave lives richer for your kindness?
My great, great, grandparents lived in Korea. Everything they did affected their children, which affected their children and so on until you have me. Here. In America. My father made the decision to not be like his father, who basically failed at fatherhood: gambled, left the family in debt, etc. My father chose to do the opposite. Because of his decisions and hard work, my siblings, mother, father and I are able to live in the Land of Opportunity.
Whatever you do, whatever you leave, it’s not permanent, but it does count.
