Psychologists at Clemson University in the US surveyed nearly 200 people older than 30, asking them what advice would they give their younger self. The answers were categorised into relationship choices, education and the way they'd thought about themselves. Professor of Psychology Robin Kowalski was lead author of the study, which has just been published in the Journal of Social Psychology.
