"Bad things can happen to anyone! But today is not a bad day!" This picture book depicts a day in the life of the main character. I have fun playing, but I fall at the playground and get my favorite dress dirty, and I argue with my friend over the order of playing with toys. I even get a word wrong on a quiz from my teacher. In the end, I cry, saying, "Today is really a bad day!" Then, a clock fairy appears and asks me, "Why do you keep saying today is a bad day?" Guided by the magic of the clock fairy, I reflect on my day. The teacher who hugged me when I fell at the playground, the friend who apologized to me first after our argument, and my great performance in the quiz with my friends! Only then do I realize that not everything in my day was bad. Bad things can happen to anyone, but they don't determine how we feel today. The main character grows a little more as they learn this lesson. "A lovely picture book that helps children see their day from multiple perspectives" - Professor Cheon Geun-a, an expert in child and adolescent development, shares the 'power of resilience.' Research shows that children over 24 months old can feel emotions similar to adults due to brain development. However, they still struggle to understand the causal relationships behind emotions, so they remember their day based on the 'feelings' rather than 'events.' Which feelings do they remember the longest? Generally, negative feelings are stronger and last longer than positive ones. Psychologists refer to this as 'Negativity Bias.' It's not easy for adults to shift their mindset once they fall into negative emotions, and it's even harder for children to handle negative feelings adeptly. Children can easily accept an entire day as a 'bad day' due to a small argument with a friend or a minor disappointment. If this emotional recognition is repeated, fleeting frustrations or anger can solidify into negative memories of the whole day and even affect their self-evaluation. Therefore, it's crucial for children to experience acknowledging their negative feelings rather than suppressing or eliminating them, and then to look back on their day and shift their mood. This experience becomes the first step for children to grow into resilient adults. Professor Cheon Geun-a, who reviewed this book, states that "Even if bad things happen, it doesn't mean it's a bad day" delicately addresses this point. This book allows children to view their day from multiple perspectives without denying their negative feelings, naturally fostering the ability to find balance among various emotions. Additionally, it conveys the message that shifting perspectives can change the memory of the day, all at the child's level. Does your child get overly upset about trivial matters? Do they easily give up when things don't go as planned? Do you feel heartbroken seeing them dwell on minor mistakes and torment themselves to achieve perfection? If so, read this gentle picture book together. They will learn that it's okay for a day not to be perfect, to accept their feelings in the moment without denying or suppressing them, and to handle their emotions through a shift in perspective.
