If you have the feeling of choice, if you feel free, you will be better off. And when I say better off I mean that if people feel they have control over their lives, they call in for fewer sick days from work. They have a lesser probability of having a heart attack or stroke. They live longer. They're happier.

You know, you take a little infant and you turn on the music mobile on their crib and you find that if you give them a music mobile which turns on automatically versus a music mobile in which - if by chance their little legs or their little hands accidentally touches it - turns on they're so much more excited if by chance it turns on because they touched it, so that desire for control over their environment is... really appears from very early on and if you look at children's first words, "no, yes."

People will make worse financial decisions for them if they're choosing from a lot of options than if they're choosing from a few options. If they have more options they're more likely to avoid stocks and put all their money in money market accounts, which doesn't even grow at the rate of inflation.

Life hands us a lot of hard choices, and other people can help us more than we might realize. We often think we should make important decisions using just our own internal resources. What are the pros and cons? What does my gut tell me? But often we have friends and family who know us in ways we don't know ourselves.

I put out a good 10 different types of drinks for them and they just said, "Oh, okay, so it's just one choice." One choice? I gave you Coke, Pepsi, Ginger Ale, Sprite. They saw that as one choice. Now why was that one choice? Because they felt, well, it was just all soda.

Too many choices can overwhelm us and cause us to not choose at all. For businesses, this means that if they offer us too many choices, we may not buy anything.

The saying goes that history repeats itself; personal histories do the same. We can gather the lessons of others' lives through observation, conversation, and by seeking advice. We can use the automatic system to find out who the happy people are, and the reflective system to evaluate how they got to be that way. Pursuing happiness need not be a lonely endeavor. In fact, throwing in our lot with others may be a very good way of coping with the disappointments of choice.
