Here is an interesting chicken and the egg problem. Which came first? This quote from Dr. Benjamin Spock or the one from John F. Kennedy about choosing to go to moon. As of yet, I have not been able to find the original date for this version of the quote. With the original publication of this book in 1946, it is possible that JFK borrowed this quote from Dr. Spock. I went with the image of the book that I remember from my childhood. I always felt like it was kind of like my users manual and wondered what secrets it held inside. I used the color picker tool to match the cover of the book.
