That’s a lesson we can all learn: the more we have, the more we want. And the only cure is to break the cycle of relativity.

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.

A very simple bad decision is to get into debt. And that is very expensive.

Do you know how much money you would save if you changed your light bulb to compact florescent light bubs? How much would you save if you decreased your temperature of your house in the winter by one degree, or increase it by one degree? We just don't know these numbers, but I think displays could make it a memorable change in terms of attention, and also help us translate it in terms of concrete ways on what you can get.

Motivation, basically getting people to be happy at work, everybody - everybody benefits.

Money actually becomes even more difficult than other things because it's very hard to imagine what the benefits are to saving. So, imagine that you see a new bicycle, a new pair of shoes, or something today. You know exactly what you are giving up if you are not buying it, what are you gaining in the future if you are not getting it. So, you are giving up the bicycle today, what is it in the future? What will happen if you send another $1,000 to your retirement fund? What difference will it make? It is very, very hard to figure out.

Who would you trust right now? Which bank would you trust? Which investment would you trust? Do you really want to put your money; do you want to suffer more of these losses that we just had? You know, these volatility that we see is just unexplainable by any rational standards. Nobody has any clue about how to explain this, and nobody wants to experience that. So, we hold more money back, we don't necessarily want to invest in the market and by default, people are saving more.
