It's a good read, proven without a doubt, but it won't make any difference to our OP over here...
My take on this thread: OP is trying to get that endorphine hit from buying things to extend beyond the 10 minutes it normally lasts by boasting, maybe validation that other's have the same tendancies (which we all do to some extent).
I'm the same TBH, I spent my cash on making my house warm, efficient and with my own power. It'll take 20 years to pay off, has very few direct benefits, but I get huge satisfaction every day knowing I'm not cold, burning gas at great expense and the power will stay on. It's similar, but with a focus on utility and on a much longer scale...
