Learn from mistakes
Can we learn from mistakes and become smarter? I'm sure we do reckon some stupid things we did over time and try the best we work. Nevertheless, we seemed to be programmed to have certain preferences and personalities that we are unable to make a "complete makeover". An university professor always asked us to reflect on what we have learnt from reading some books and journals. I feel like I should sit down and reflect more on what I have encountered in life, no matter it is a good or bad thing.
