TBH Bath I think I detach from it by having enough money. sounds counterintuitive but here goes.

Maslow (a famous psychologist) talked about a hierarcy of needs. Its only when needs like air, food, shelter, etc are met that you can even think about more spiritual ones. So I think because I have enough, and if I wanted to I can "have" much more than I have got, I feel like I am making a choice. So not wanting, not buying and not accumulating is an expression of my personal power over my life.

It sounds really egocentric but if you CHOOSE not to buy things, suddenly you stop wanting them, and they loose their appeal.

I HATE the idea of buying lots of plastic crap for my son just because it's christmas or whatever.
I am so with you. A good way to think about toys is "play value". IMO if a kid is going to get less than 50 hours of play out of something then you have to seriously question if its worth it. Take those (incredibly cool looking) robotic dinosaurs in the catalogues ATM. Can you imagine how HAPPY a kid would be to get one of those for Christmas!!!

And can you imagine where it will be on new years day? My guess is in the spare room next to the luggage set bought at the boxing day sales and behind the foldout bed that still hasn't been put away since Grandma went home.....
