From childhood, we were taught to strive for a life without regrets, but in reality, things often go against our wishes. Since regret is a common feeling, what is the thing we regret most in life? According to Western studies, the most regretful thing is, surprisingly, education, ranking much higher than career, love, upbringing, and security (Streep & Bernstein, 2015). Fries et al. (2005) also found that regardless of whether they had clear academic goals or not, as many as 90% of students reported experiencing confusion and conflict over course selection, which had a profound impact on their cognitive experiences and academic emotion.
