     My dad, Greg Newman, had wanted to be a race  car driver, but things didn't work out for him.So

I guess having a son who could become a race car driver was the next best thing.Don't get me

wrong-Dad didn't push me into racing.In fact, when I was about 10 years old, my dad was afraid that

driving a car wasn't my dream.So he took the racing away from me.I wasn't very happy with that decision.It wasn't long before Dad realized that racing was what I loved.

     At four, Dad bought me my first Quarter Midget (袖珍赛车)  and that's really where it started for us.

Back then, Dad coached me.He would stick out (伸出) his footin the path of the race car, and then tell

me to exactly hit his foot.By repeating this again and again, Dad believed that I would be faster and

sharper on the race track.

     Dad worked really long hours at his car repair business to make money so that I could race each

weekend.I can remember that every night before he turned off the lights in the garage, Dad would tell

me:"Don't forget to kiss your race car good night." He was trying to teach me that if I show respect, it's

returned.He wanted me to show thankfulness and respect for my race car and for all the hard work that

we and many others had put into the dream.

     My dad, my mom and my sister gave up a lot of things to help me race.For us, there was no better

moment than winning the 50th running of the Daytona 500 in 2008.That evening in February 2008, I

knew I had gotten a good push.I could hear the excitement.My father couldn't speak a word, and when

he got to  Victory Lane (车道), he nearly knocked me over and  gave me such a big hug.
