No, but nostalgia can have different definitions. Merriam-Webster defines it in a partially negative light. I meant in the Gatsby sense, you beat on against the current. Do I want to relive my childhood? Hell fuckin' naw. But even when life is good now I can't help but feel... bored. It's like nothing really gets my blood racing anymore. The frontiers have been conquered. I've laid it all to rest. But then all of a sudden I hear a track from my friend's band almost a decade ago all the emotions come flooding back and it's too much to bear. I'm not sad it's over, I'm glad it happened but it's that feeling of having gained and lost some infinite thing.
Gotcha. I see what you are saying. You know, kleinbl00 has commented a couple of times with numerous studies that say, basically, whatever you were listening to, eating, enjoying when you were about 18-23, is what you will ALWAYS think of as "good" for the rest of your life. Now I'm in my 50s, I think back to those years - 1987-1993 - and realizing how true this is. Mine also extends a little earlier, probably back to 1983 or so, because I grew up with a group of guys who were about 3 years older than me. So I was far more in that demographic, and had very little in common with people exactly my age. I still think that you can decide that "nostalgia" is a good thing... embrace it for what it is: a biomechanical/societal programming that incentivizes you to see one particular phase of your development as superior over others. So you can look at that, marvel at the complexity of the human organism, and also know that it isn't necessarily "true", either. I'm not calling you wrong, or anything... just wanting to give you another way to view nostalgia as a positive thing, and not a condemnation of your current place or accomplishments or phase in life. <insert heart emoji here>
