I am getting older. Only one day at a time yet the process is irreversible. This causes me to rethink some of my long term goals supposedly finished when I am young. Not dismiss them, but reevaluate. It is important for a goal orientated person like myself to use the newest data to add to the goal and determine the progress from here. For example, a sail boat going across an ocean may sail with the wind one day, into the wind another day, and across the wind on a third day. It might even end up in the doldrums, windless, too. Yet crossing the ocean is still the goal. If the boat gets off course maybe it will arrive at the wrong port, but the goal is still a continent in general, even if the details of the arriving city change.
The point is, use the most recent data of where you have been recently and how it fits into where you want to go and you will have a better idea of how to sail to your destination.
