Following on from my suggestion to you that you practice mindfullness for golf, this article came to my attention.
Happiness is found by living in the now, according to a major study into mental wellbeing. But the study also found that people spend nearly half their time thinking about something other than what they are actually doing.
Psychologists at Harvard University collected information on the daily activities, thoughts and feelings of 2,250 volunteers to find out how often they were focused on what they were doing, and what made them most happy. They found that people were happiest when having sex, exercising or in conversation, and least happy when working, resting or using a home computer. And although subjects’ minds were wandering nearly half of the time, this consistently made them less happy. The team concludes that reminiscing, thinking ahead or daydreaming tends to make people more miserable, even when thinking about something pleasant. The Authors write in the journal Science. “A human mind is an unhappy mind. The ability to think about what is not happening is a cognitive achievement that comes at an emotional cost.” The Guardian
Would you play better golf if you were happier on the golf course?
