Summary
The interview with Bob Mack, a positive psychology expert, focuses on the relationship between happiness and success. Bob Mack emphasizes that happiness leads to success, rather than the other way around. He advises finding happiness in the present moment and not delaying it for the future. The common mistake mentioned is outsourcing happiness to external factors, rather than recognizing that true happiness is within a person's control. The interview also discusses the paradox of people in third world countries being happier than those in the first world, despite having fewer material possessions.
