Along the same line is this TED talk by Sheena Iyengar on the Art of Choosing.
About the talk:
Sheena Iyengar studies how we make choices -- and how we feel about the choices we make. At TEDGlobal, she talks about both trivial choices (Coke v. Pepsi) and profound ones, and shares her groundbreaking research that has uncovered some surprising attitudes about our decisions. Hope you Enjoy.
