He may lose his possessions, his home, his loved ones, but if he holds on to a story about choice, he retains the ability to practice choice.
Sheena IyengarThey [people] start asking themselves "Well which one is the best? Which one would be good for me?" And all those questions are much easier to ask if you're choosing from six than when you're choosing from 24 and if you look at the marketplace today most often we have a lot more than 24 of things to choose from.

Everybody starts choosing in accordance with looks because that becomes the easiest criteria by which to weed out all the options and decide "So who am I going to say yes to?"
