David was in the basement of the library at Ohio State University looking across mountains of research reports that would never reach the people who most needed them. There was research on life satisfaction, relationships, prosperity, parenting, all manner of good things. But no regular person was ever going to come to the basement to read about how they could make their lives better. And if they did, they would find the reports filled with stuffy jargon produced by academics writing to impress other academics. Later that day, David launched a project to bring that research to people who could use it. Today, David is known internationally for translating powerful research findings into practical advice anyone can apply to their daily lives. Published in more than two dozen languages, David’s books show that a more satisfying life can be had with small, sustainable changes in our actions and attitudes.
