Interview with Shawn Author (author of 'The Happiness Advantage'). Link to podcast page. He is a researcher on positive psychology, talking about work he did at Harvard and various blue chip U.S corporation (Adobe, Morgan Stanley, Google).
The main point he is trying to make is that it is a misconception that humans are at their best when under stress. The interviewee believes (and researched) that actually individuals that are happy and positive outperform the stressed individuals.

Social support is the greatest predictor of somebody's happiness and success in a time of challenge (correlation 0.7).
Do for 21 days in a row. Change the way the brain processes pattern, focuses more on positive things. Apparently the (positive) changes can last for up to 6 months.
(They were not clear at all what were the measured benefits of this, but implied it raised happiness.)
(Again, they were not clear at all what were the measured benefits of this, but implied it raised happiness.)
