Kierkegaard's idea of "repetition" actually speaks very directly to the topic of this larger discussion. Many ways to interpret his writings here, and I am no trained philosopher, but he seems to write about how repetition is not truly possible - that encountering a once-new thing for a subsequent time is tainted by recollection - dulling the experience essentially. I think he also suggests that cultivating a certain mindset can re-novelize life but I am thinking not many achieve that.
