i cannot see far enough ahead to see what is going to happen on that journey. when i am traveling i always look back to see where i have been (where i am) - that is a part of being human (looking at my own behavior). thus, i must be aware of everything that has happened (know my history) and be alert to that which has not yet occurred.
