What “counts”: the things we mean not to count and/or think completely incidental to what we do is what is historically significant about us, I believe Tolstoy would say. Whatever we do not choose is what historically counts.
Perhaps in the world of today this is like saying: what you do online (what you may learn, what you may express) is significant only to yourself, but the data that may be extracted from what you do, your clicks, that is history. Big Data = historical force.
