One of the things I’m very interested in is how positive emotions (such as joy, happiness, etc.) can help football players make better decisions. One of the many things that positive emotions do is that they fuel psychological and physical well-being. That is, positive emotions help players cope with set-backs and the negative emotions associated with them. Put differently, positive emotions promote resilience. A fantastic whiteboard explanation of resilience – and very relevant also for sport, but really for life in general – is here given by Brian Walker, CSIRO, sustainable ecosystems, Australia.
