This learning material is a TEDTalk by Dan Gilbert. It examines the psychology underlying our self-perspective on values and personality as we age. In his talk, Gilbert elaborates on the idea that while humans believe they are not very likely to change social circles or personal preferences over a ten year time period, the opposite is actually true. A quote from Gilbert: "Human beings are works in progress that mistakenly think they're finished."
