Desire and Aversion: Should Anders focus on winning or on personal improvement?

Anders has always wanted to be the best player on his school's soccer team. He's been practicing hard and feels confident. However, there's a big game coming up, and Anders is worried about losing. His friend Eun-Kyung notices his anxiety and suggests that instead of focusing on winning, Anders should concentrate on improving his skills and enjoying the game. She reminds him that he can't control the outcome, but he can control how he plays. As the game day approaches, Anders feels the pressure from his teammates who expect him to lead them to victory. Anders now faces a choice: (A) focus on winning the game and meeting his teammates' expectations, or (B) concentrate on his personal improvement and enjoyment of the game.
