It turns out that it doesn’t matter much what activity a person is doing. Typically fun activities didn’t correlate much with happiness. Instead, what matters is whether you are paying attention to what you are doing. Focused attention was strongly correlated with feeling happy, whereas having a wandering mind was usually accompanied by unpleasant feelings. Interestingly, human beings are very prone to mind wandering.
