In Haruki Murakami's "Dance Dance Dance," the author emphasizes the importance of effort and attitude in achieving goals. He suggests that pouring one's heart into endeavors makes a significant difference, highlighting that commitment can lead to success, but acknowledges that there are limits to what hard work alone can accomplish. True happiness, according to Murakami, requires consistent effort, yet he points out that ultimately, some aspects of life are governed by luck.

This perspective encourages readers to strive for their aspirations while recognizing that not everything is within their control. Murakami's insights reflect a balanced understanding of the relationship between hard work and the unpredictable elements of life, reminding us that while dedication is crucial, external factors can also play a pivotal role in our achievements and happiness.
