Years ago there was an excellent Calvin and Hobbes toon. In it, Calvin was either writing a journal and/or taking photos or drawing pictures. Hobbes asks him why he's doing it. Calvin replies that he is pre-shaping his past for his eventual run for the Presidency. As I recall it, it entails a portrait of a noble young Calvin, studying a book.
If any reader can find a copy of that toon, we'd love to see it again.
The reason it came to my mind today is obvious.
