The good memories we have of the past always seems more glorious than it really was. The more distant the past, the more glorious the good memories we have seem. The fact is many of us like to look at the past from time to time. But because it exists in our heads, our perception of events can be subjective.
Maybe the past was rosier than it is now. Maybe it was not. One thing is certain the past is the past. Living in the past or trying to recreate the past is hardly possible. Unless we realize this, we may face disappointment or even danger.
