It's amazing how our passions can evolve so much over time.
How nice that you remember that Green Lantern figure with so much affection, it seems that it had a special value for you beyond being just a toy.
Perhaps you could try to focus on a few figures at a time, as you did as a child, and rediscover that special bond with each one.
Sometimes less is more, and true enjoyment is in the connection we achieve with what we have.
I hope you can get that joy back soon.
