“Life is divided into three periods, past, present and future. Of these, the present is short, the future is doubtful, the past is certain. For this last is the one over which Fortune has lost her power, which cannot be brought back to anyone’s control. But this is what preoccupied people lose: for they have no time to look back at their past, and even if they did, it is not pleasant to recall activities they are ashamed of.”
