There is an ongoing experiment where people are phoned at random times and asked 3 questions. What are you doing? How immersed are you in what you are doing? How satisfied are you? Consistent results show that those people who are fully engaged in present moment experience are generally more satisfied than those who are distracted, regardless of what they are doing.
This means that someone who is mindfully washing the dishes is more likely to say they are happy than someone on a cruise in the Caribbean but distracted. Or someone dealing with a difficult situation may be more satisfied than someone having a day off work but thinking about the past or the future.
