One financial lesson they should teach in school is that most of the things we buy have to be paid for twice. There’s the first price, usually paid in dollars, just to gain possession of the desired thing, whatever it is: a book, a budgeting app, a unicycle, a bundle of kale. But then, in order to make use of the thing, you must also pay a second price. This is the effort and initiative required to gain its benefits, and it can be much higher than the first price.
[…] But no matter how many cool things you acquire, you don’t gain any more time or energy with which to pay their second prices—to use the gym membership, to read the unabridged classics, to make the ukulele sound good—and so their rewards remain unredeemed.
[…] This scarcity feeling creates one of the major side-effects of our insurmountable second-price debt: we reflexively overindulge in entertainment and other low-second-price pleasures –- phone apps, streaming services, and processed food — even though their rewards are often only marginally better than doing nothing.Everything Must Be Paid for Twice by David Cain
