Reporting their findings in The Journal of Social Psychology Robin Kowalski and Annie McCord at Clemson University have done just that in two surveys of hundreds of participants on Amazon’s Mechanical Turk website. Their findings show that people’s advice to their younger selves is overwhelmingly focused on prior relationships, educational opportunities and personal worth, echoing similar results derived from research into people’s most common regrets in life. Moreover, participants who said they had followed the advice they would give to their younger selves were more likely to say that they had become the kind of person that their younger self would admire. “…[W]e should consult ourselves for advice we would offer to our younger selves,” the researchers said. “The data indicate that there is much to be learned that can facilitate wellbeing and bring us more in line with the person that we would like to be should we follow that advice.”
