To take the moment one second at a time, to thrill in either success or hopefully recover from the failures is the important approach. Otherwise, we remain trapped in the false hope of going backwards,a prospect that while interesting to contemplate, remains an experience only possible in dreams. It may have transpired in that previous moment with slightly different details, but it was nevertheless similar. In the universities, similar students have attended the same class. The same homework has been already.
Details change, but nothing is fundamentally new.
All will happen again. In this world, there can be minor diversion from the past, but the fundamentals remain the same. There can be no release from the cycle. In the city park, people walk hand in hand with their lovers, children, family, enjoying the last few breaths of summer. They hurry to catch the remaining sunrays before the approaching gloomy winter, not thinking that this has happened here before.
