"My body is like breakfast, lunch, and dinner. I don't think about it, I just have it."
"The mind is the limit. As long as the mind can envision the fact that you can do something, you can do it, as long as you really believe 100 percent."
"Milk is for babies. When you grow up you have to drink beer."
"I have to give the audiences what they enjoy seeing while I try to bring in a little something new"
"Strength does not come from winning. Your struggles develop your strengths. When you go through hardships and decide not to surrender, that is strength."
"You know, nothing is more important than education, because nowhere are our stakes higher; our future depends on the quality of education of our children today."
"People should make up their own mind about what they think of me."

"Failure is not an option. Everyone has to succeed."

"This whole idea of him going to USC to study business and economics is because he wanted to be an entrepreneur," Arnold told ET's Ashlan Cousteau in July 2015. "He figured out that I have always taken care of my own money. I've never had a business manager and I'm the only one in entertainment that never lost any money. He wants to make sure he's falling in the same category of 'let's worry about how much money we make and also how much money we keep.' That's very smart."
