The more cashless our society becomes, the more our moral compass slips.

We need to believe that we're good people, and we'll do just about anything to maintain that perception.

The real issue is, how much goodwill do you invest in the work? And goodwill is not something that we can buy with money. It's very hard to buy goodwill with money.

We all want explanations for why we behave as we do and for the ways the world around us functions. Even when our feeble explanations have little to do with reality. We’re storytelling creatures by nature, and we tell ourselves story after story until we come up with an explanation that we like and that sounds reasonable enough to believe. And when the story portrays us in a more glowing and positive light, so much the better.

When you're in pain, tomorrow doesn't exist - just the pain - and the only thing that you want in the world is for it to go away.

individuals are honest only to the extent that suits them (including their desire to please others)

Once you break the social norm and create a new social norm, all of a sudden it can stay with us for a long time.
