I think we could get people to both be more productive and happier. We're less productive as individuals. We're less productive as companies, and we're more miserable.

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

With money we really fool ourselves. We are our biggest enemies with money and there are some things we can do about it. Automatic deductions are a wonderful thing. But ideally, you should wait until the end of the month, you can see how much extra money you had, and you should put that in your savings account. We don't do that too well, and if we did that, we would never save. So, what we do, is we take money out of our pocket into the saving account at the beginning of the month, take it outside of our control and as a consequence, we spend less and we save more.

Linking financial element to energy consumption I think has a huge role if you think about a display instrument that could teach us about what we are using, how much it costs us, how much it is saving, and therefore change our decisions.

The people who need to overcome temptation to the highest degree have the hardest time doing it.

We don't really want a huge house, but we want the house to be slightly bigger than our neighbors, and a car that is bigger than our neighbor's, and they're going on vacation that's slightly more expensive, and this escalation happens that things got out of hand.

We are all far less rational in our decision-making than standard economic theory assumes. Our irrational behaviors are neither random nor senseless: they are systematic and predictable. We all make the same types of mistakes over and over, because of the basic wiring of our brains.
