Replace the “buyer’s high” an “investor’s high”
“The next time you want to buy something, instead consider buying stock in the company that makes it. Rather than buy a Coke, buy a share of Coke stock.”
Of course it’s not exactly that simple (they don’t carry stock shares at the mini-mart), but it’s the sentiment I agree with. Once you realize you have enough, extra income can be put towards investments instead of buying more stuff.
