We should not fret for what is past, nor should we be anxious about the future; men of discernment deal only with the present moment.

The past is a rich resource on which we can draw in order to make decisions for the future, but it does not dictate our choices. We should look back at the past and select what is good, and leave behind what is bad.

Neither a wise man or a brave man lies down on the tracks of history to wait for the train of the future to run over him.
