Even though Vinny was a great soccer player, he had never run a race in his life. So he was floored when Coach Briggs asked Vinny if he had ever thought about running track. "Me? But I don't run races, sir. I just place soccer. I would be in over my head running track!" Vinny said.
"You race against other players in soccer, don't you? So running is a piece of cake," Coach Briggs said. "This is just a little faster, and you don't have to kick a ball at the same time. With my help, the sky is the limit! It might even make you a better soccer player."
After thinking it over, Vinny agreed to come out to the next track practice. The first day, Vinny realized track wasn't as easy as it sounds. Because Coach Briggs thought him to be a natural runner, he threw Vinny out of the frying pan and into the fire. Vinny had to run against the school track star, Jose. Jose easily beat Vinny, and Vinny was embarrassed to face the team the rest of the practice.
After practice, Vinny approached Coach Briggs. "Look, I appreciate the chance, but track is just not for me. Soccer is easy and fun; track is hard, and I am just no good at it. I think I should just stick to soccer."
"Vinny," Coach Briggs said. "I never said track would be easy, but it has only been one day. Whenever you try something new, you have to go for broke. It won't always be easy, but I believe you will be a great runner one day. Maybe you will even be a star."
