Agreed - I find I spend almost the same time on small decisions as large, and let the default (subscriptions, extra cars, storage) ride. That's turning the decision into a drama that befalls you (and avoiding those that don't). Or you find yourself down or up become cheap or profligate.

So, what big spending is adaptive? Better to drive decisions objectively based on future value.

Some scenarios:

- It lasts a long time, and you'll need to do it anyway. Best to get it early and enjoy it longer - for iPhones, cars, houses, marriage...

- It lasts a long time and you use it daily. Always pay for what you'll be glad to have: good socks, a powerful computer, a nice view.

- Your beloveds needs to know if you care more about money or them. Choose them.

- Something expresses your values: you appreciate an artist's work, so you pay good money for it. Some panhandler is stoic, so you give him a hand. (Just be careful about posturing.)

Another mindset is to think of your money as family (writ large) money, and invest in the future of family or friends. It's as much a vote of confidence as an injection of cash, and it helps you detach from the needy instrumentality of the money to consider what's best for their future. That's the weirder phenomenon: trillions held by baby boomers until they die (just in case), while their progeny waste time in terrible jobs and narrow circumstances for lack of investment. That's maladaptive hoarding.
