The Value of a Memory

"Past experience is less valuable as time goes by" - Econ of Strategy Textbook for Prof Smith

But as my friend Kelly Blaes keenly asked, "Can a past experience become more valuable?"

The Great Gatsby comes to mind. I would immediately say yes. But past experiences become less valuable for two reasons. 1) It is no longer useful to us, and 2) The service of the memory no longer fascinates us. If Gatsby had gone to war and come back to fall in love with someone else that wasn't Daisy, the memory of Daisy would have become less warm, less motivating, less...useful. And because it becomes less useful, the memory would no longer fascinate him and he would move on to create more valuable memories and slowly forget the first.
"If your wife died, the memory of her would become immediately more valuable to you. Mainly because you want to hold on to that memory, and all you have left to go off of is the past." - Kelly backing me up again. I would pessimistically remark, "Until he found someone else."
