I was living, growing up in a very traditional household and yet at the same time I was going to school in the United States where I was taught the importance of personal preference, so at home it was all about learning your duties and responsibilities whereas in school it was all about well you get to decide what you want you want to eat.

So it was constantly going back and forth between these two cultures that kept raising the question, well, how important is personal freedom? And I think that has always been of interest to me.

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.

Most of the time you should use reason, there is no doubt about that because gut often makes us susceptible to lots of different biases, particularly if what you're deciding is something that you really, that expertise can be brought to bear on it, there is a way in which you can align the odds, so then you should really use reason.

You know, or three kinds of ice cream bars and you'd see this and like this... okay they could clearly benefit from some more choices and I remember having these discussions with the Japanese because they you know they often like to go to Hawaii for vacation because it was definitely much cheaper for them and I would ask them, "So when you go to Hawaii, you know do eat all these other things?"

My child's first word was "more," but and it's all about, "I want." "I'm going to tell you what I want and what I don't want." It's about my desire to express my preferences. And that is really innate.

You know, whether it be humans or animals. So even humans - before we can speak or we can understand a baby's cognition - they're already showing us signs that they want choice.
