The document tells a story using three pots on the stove to represent challenges in life. The first pot holds carrots that soften when boiled, representing people who lose strength when facing difficulties. The second pot holds eggs that harden inside when boiled, representing people who become bitter and lose warmth when facing challenges. The third pot holds coffee beans that change the water's color and aroma when boiled, representing people who learn and make positive changes when facing problems. The moral is that we should aim to be like the coffee beans and use life's difficulties to grow stronger rather than become weak or bitter.
