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.

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.

The quality of health care continues to improve, and people are living longer, but these developments mean that we're likely to eventually find ourselves in a situation in which we're forced to make difficult choices about our parents, other loved ones, or even ourselves that ultimately boil down to calculations of worth and value.

We began to look at "Why is that?" And a large part of that has to do with the fact that when people have a lot of options to choose from they don't know how to tell them apart. They don't know how to keep track of them.

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.

Like, people are less likely to invest in their retirement when they have more options in their 401K plans than when they have fewer.

What's interesting is that the way we go about finding our marriage partners today is quite different from the way it used to be in this culture.
