You're the product of 8 great-grandparents, 16 great-great-grandparents, 32 great-great-great-grandparents, and so on.    
Keep multiplying by two.    If you average 25 years between each generation, you'll discover that just 500 years ago,there were 1,048,576 people on this planet who were beginning the production of...you.

With such an enormous investment in the creation of you, isn't it appropriate for you to justify such heroic efforts by making the most of your opportunities? We don't refer to what you're going to do someday, rather, what efforts you invest on this very day to do one, maybe more than one thing,

When you grasp that you are rarer than one in a million, you'll see how important you are; how important your efforts are in the short and long run. So, tell me, and all of us. Better yet, tell the most important face you'll ever see in a mirror,   mathematically rarer than one in a million.
