Managing an investment fund: selling lucrative opportunities to investors.

Copywriting: selling the needs as well as prospects (sometimes illusions) of becoming beautiful and high-class to consumers.

Being a doctor: selling hopes to patients (sometimes even when there aren’t any).

Going on job interviews: selling yourself (which I have been doing a lot recently) to employers.

Going on dates: selling the loving, virtuous and resourceful wife image to the other, who’s also trying to get you to buy his faithful, protective and filthy rich (or potentially so) husband image.

Wearing LV, driving Lexus, living in Berverly Hills mansion: selling credibility, translated as "I’m capable of paying back whatever you loan me"

Making friends: selling or rather, exchanging promises of comfort.

What else do we sell?
