When Sheena Iyengar went to Spain, people sometimes came up and asked her for a lottery ticket. “Because that is what blind people do in Spain,” she explains. “They sell lottery tickets. And when I was in Japan, random people would come up to me and take my hands and start putting them on their backs or on their necks because they expect blind people to perform magical massages.”

These people would have been stunned to learn that though Iyengar is blind, she is a noted researcher, a professor at Columbia and the author of a critically acclaimed book ‘The Art of Choosing’, in which she dissects and analyzes choice – the ability one has to take on destiny – or even competing brands of cola.

In life, how much can you choose and how much is pre-destined? Can you fight circumstances or is your role pre-ordained?And if you have the power of choice, how do you choose wisely?
