Predetermined futures????

Two weeks ago I picked up a book, "Dreams from my Father: A story of Race and inheritence" by Barack Obama. On reading the chapter on origins I discovered that the young man had quite an ancestry including Christopher Columbus Clark. Then he had been the first black president of the Harvard Law Review.....and now he seeks to be the first black American president of the U.S of A? I could not help but think that from the time he was a child, he had conceived the idea of becoming a highly influencial person- I mean are all the above coincidences? And is it a coincidence that the first version of the book was written after his graduation and it included all his supposed scandalous ways of his youth which in turn meant that no matter what any of his oponents ever claimed in his future life, he had already published it for the world. Having had this discussion with a friend, I was told to read " The Mustered Seed" and see how people plan their futures.........hmmmmm oba what happened to me?
