In the Journal of Social Psychology, two U. S. researchers published the first serious study of a question that seems to be troubling millions. Almost every     1     from Bill Gates to Kesha, is required to have an answer: What advice would you give to your younger self?

Robin Kowalski and Annie McCord asked more than 400 participants, all     2     over 30. They got some entertaining replies like “Don’t marry her”. But we’re little closer to making clear the     3     that has always bothered me: What, precisely, do people take themselves to be doing when they ask themselves this question?

Pretty     4    , it rests on a paradox(悖论). You only acquired the wisdom on which your advice is based by making the mistakes you’re now advising your     5     self to avoid. For example, many respondents gave some answers “Stop being so afraid” - of failure, of other people’s judgements, of life. Excellent advice, but you’ll never feel its force until you’ve first acted afraid and seen where that got you.     6    , as the saying goes, is a harsh teacher. It makes you sit the test first and only gives you the lesson afterwards.

Of course, if “advising your younger self” were just a happiness - boosting technique to remind you of what you’ve learned in life, nobody could     7    . However, browsing the replies to the study, what you sense, far more frequently, is regret. People truly wish they had not married so young, chosen a career to please their parents, or spent the money instead of saving it. And this only brings into focus on the     8     that regret is a basically self-contradictory(自相矛盾的)emotion. You’re feeling it because you’ve grown into the kind of person who can look back     9     on what you did in the past. This means that, judged by your     10     values, you’ve emerged from your life experience better than before. Therefore you ought to be happy rather than regretful.

The important thing isn’t what you might have done differently in the past, if you had been someone that you couldn’t have been back then. It’s what you’d do now. For many people, I know, this can be a huge challenge. But unlike changing the past, it has the great advantage of not being impossible.
