Can joy improve performance?

The stylish guys over at Johnnie Walker have been dropping some informative and interesting videos as of late and we found this quick watch on positive and negative feedback while playing golf incredibly interesting. 

Sure, golf is more of a mental game than something like football, where anger and frustration might lead to harder hits and greater intensity, but overall, the idea of joy and kindness making you be better at whatever you are doing is an optimistic, nice way to look at the world.

They also did another video on whether shopping for yourself or shopping for a gift brings greater happiness. The results were as you expected, but it's still nice to see it play out with real people in a real setting.
