Oof. That's something I think about all the time anymore, especially around my fav holidays- Halloween and Christmas. I keep trying to chase that high I had as a kid, where everything felt magical; but I'm realizing more and more that that world, and that version of me, just doesn't exist anymore. It's a hell of a lesson to learn, and certainly despressing.
I think that's why I focused heavily on nostalgia for a while- collecting the things I never got or had to sell to make ends meet for my family. Now that I've mostly gotten all those things I missed or missed out on, it's a lot of future proofing. The nostalgia may be gone, but the joy is still there; even moreso after I make space for new things and feel excited about where to put it. The money aspect sucks; some may argue that anything over $0 is too much to spend on toys, but I do so happily. It's damn near the only thing I have even a modicum of control over in these crazy times, which is also why, I think, it feels even more frustrating when things sell out before you can order them or you have difficulty finding it- it feels like you've lost the last thing you have control over, and that dopamine is being held from you by forces outside your control.
It also makes sense, but is still funny/interesting to note, that as I get my anxiety/depression/trauma under control more and more, the need to absolutely positively have everything I have my eye on starts to dwindle a bit. I'm cool waiting or, worse comes to worse, not having it at all.
