If you don't specifically need the money then don't bother. The consoles always bring out a little gem now and again that is worth playing.I'm leaning more than ever towards consolidating on one platform now - PC - and foregoing both the consoles. I've got until October when PS+, Game Pass run out but I can see myself selling the consoles at that point.
Maybe just take a break for a bit. What sort of genres were you into when you first started gaming? Is there something that's current that is similar that you could pickup?
I guess the sad fact is that people just growout/burnout/find other hobbies as they get older.
I guess I'm lucky, I'm still a keen gamer at 40
