One day, Fox watched those football stars play football on TV. Fox thought, if only he wanted to play football like a football star. Then Fox went to find a football to play with. After playing, he found that football was really not easy, and then Fox didn't want to play.
Later, Fox went to watch TV and saw football players running hard on TV, which made Fox understand that you can't do anything halfway, and you have to rely on your own efforts to succeed.
