Thinking of what makes you unhappy? That's likely because of mind-wandering!
According to study, people's minds wander 47% of the time, and this is causing unhappiness, no matter where they minds are wandered off too. And NO, it is not unhappiness that causes mind-wandering either. Mind-wandering is indeed the cause of unhappiness according to this research, rather than a consequence of unhappiness. Hence, learning to stay in the present moment focusing on the task at hand is likely going to improve our productivity and quality of our lives!
