Yong Chol grew up in a well-off family, while Kwan Su didn’t have those privileges. Yong Chol was a diligent student, while Kwan Su didn’t show any outstanding academic success. The first went to university in the capital, while the second chose a provincial school. Years later, they meet in an amusement park, where the once unremarkable student Kwan Su turns out to be the owner of an expensive car, living in an elite high-rise in Seoul and closing multimillion deals. The question of how Kwan Su achieved such success, given that Yong Chol had more opportunities, comes down to their way of thinking. Kwan Su shares his experience with Yong Chol, becoming his mentor. He explains how he managed to leave the province, start investing, and build a successful business—showing that changing one’s mindset is the key to success. If it worked for him, it means it’s possible for others too, as long as they’re ready to follow his example.
