This man that the narrator met by the lake taught them many lessons about life through their conversations. He shared stories of his past successes and disappointments. The man encouraged the narrator to follow their dreams but also taught them to be humble, selfless, and make wise choices. While the man's life did not turn out as he expected, he remained positive and hoped to face what had challenged him in the past. The narrator was grateful for the wisdom the man imparted before they both continued on their separate journeys.
