"First of all, you can make the argument that there's no such thing as the past. Nobody lived in the past"

This quote by David McCullough recommends that the principle of the past is an impression. He indicates that the past is not a concrete point that can be experienced, but rather a construct of our own minds. We can just keep in mind as well as reflect on the past, yet we can not really stay in it. This idea is sustained by the reality that the past is regularly changing and progressing as we get new knowledge and also understanding. The past is not a fixed entity, yet rather a frequently moving landscape of memories and experiences. By suggesting that there is no such thing as the past, McCullough is emphasizing the relevance of living in the here and now and maximizing the possibilities readily available to us. He is encouraging us to make use of the here and now minute and also make the most of our lives.
