I enjoy TEDTalks and this one by Dan Gilbert really gives you something to think about in regards to happiness.
Harvard psychologist Dan Gilbert says our beliefs about what will make us happy are often wrong — a premise he supports with intriguing research. Dan Gilbert, author of “Stumbling on Happiness,” challenges the idea that we’ll be miserable if we don’t get what we want. Our “psychological immune system” lets us feel truly happy even when things don’t go as planned.
Perhaps this is why entitled people, like Bridezillas, never really seem happy despite getting what they want.
