How to chart a life? Measure its profits? Its losses? I think it is by the challenges taken on, the difficult trades made, win or lose. In the end, no matter how much you have managed to document, most of what you know is lost. Much that is great cannot be explicit, it must be tacit. Only a very dedicated spirit would wish to return. I am not so very far away myself. I choose oblivion. Once around was almost too much to bear.
