Question

School started like 3 days ago, and im already getting homework. I need help with finding the theme to this story. 2. Justin was jealous when his cousin Cassie was named valedictorian of her class. "Some people are just born smart," he told himself later as he watched TV on the couch. He had not been with Cassie all of those times when she studied late into the night. Justin was also jealous when his cousin Victor was elected class president. "Some people are just more popular than others," Justin told himself while playing video games on the couch. He had not been with Victor while he tirelessly campaigned, listened sympathetically to the problems of others, and treated everyone he knew with kindness and respect. When Justin's cousin Matthew became the quarterback for the varsity squad, Justin was envious. "Some people are just more athletic than others," he told himself as he played around on his computer. Justin had not been with Matthew while Matthew trained relentlessly to develop his athletic abilities. "One day something lucky will happen to me too," Justin told himself as he snacked on junk food.

What is the theme of the story?
