What keeps us happy and healthy as we go through life? If you think it's fame and money, you're not alone – but, according to psychiatrist Robert Waldinger, you're mistaken. As the director of a 75-year-long study on adult development, Waldinger has unprecedented access to data on true happiness and satisfaction. In this talk, he shares three important lessons learned from the study about how to build a fulfilling life.

The uniformity of her findings suggest that graphic communication, and the ability to preserve and transmit messages beyond a single moment in time, may be much older than we think. Watch »

Quote of the Week
“
Books have an extraordinary power to take you out of yourself and into someone else's mindset, so that, for a while at least, you look at the world through different eyes. That can be an uncomfortable experience. But it can also be really enlightening."
