Most things that couples disagree upon aren't worth more than a day's combat.

This is the essence of intuitive heuristics: when faced with a difficult question, we often answer an easier one instead, usually without noticing the substitution.

In strategic decisions, I'd be really concerned about overconfidence.

If people can construct a simple and coherent story, they will feel confident regardless of how well grounded it is in reality.

One emphasis of my research has been on the question of how people spend their time. Time is the ultimate finite resource, or course, so the question of how people spend it would seem to be important.

If you can't take the time for a vacation right now, or even a night out with friends, put something on the calendar - even if it's a month or a year down the road. Then whenever you need a boost of happiness, remind yourself about it.

We are often confident even when we are wrong, and an objective observer is more likely to detect our errors than we are.
