This talk runs 20 min and I realize most of you won’t invest that much time. And I’m not sure I can summarize, but let me try: There are the experiences in our lives… and our memories of those experiences. And they are not the same. Our “happiness” ( a word that no longer has much useful meaning) has more to do with the latter.
As for the future? Kahneman says “we think of our future as anticipated memories.”
My understanding (based on my reading on this topic): The past and the future are delusions, stories. Created by the mind to protect the ego. Only now -this moment- has any reality.
