In racing, things start coming up quicker, and the slipstream is stronger, so even judging in the mirrors how quick the cars are approaching isn't always easy.

It's a complex sport; you're always learning.

There have been times in my career when people thought I was a pushover, especially as they saw me as this smiley guy.

I had a very successful 2014, but I have got to keep aiming for bigger and better things, so the world title is my goal.

My family was really big on college, and it was hard for them to stomach that I was going to be a hairdresser.

Grissom comes from a place where we know he had a deaf mother, he was raised in a silent household, on some level, had a father who potentially was not around and he learned what he knew by himself in the back yard, with bugs and animals. He's not comfortable being a supervisor and that's his problem.

I've helped many, many, many children, thousands of children, cancer kids, leukemia kids.

My family and school life are important to me.
