If you can be tricked into being dissatisfied, you can trick yourself into delight.

A friend recently rekindled a love of Air Jordans, but started second-guessing if this was an authentic desire, or one just cultivated by enough subtle marketing that it felt real. (Or a healthy dose of Tinker in his prime).
Perhaps we'll all come to mistrust ourselves, feeling that we're not really living freely, but swayed by the Satanic whispers of algorithms.
